BACKGROUND
Metathesis is a catalytic reaction generally known in the art that involves the interchange of alkylidene units among compounds containing one or more double bonds (e.g., olefinic compounds) via the formation and cleavage of the carbon-carbon double bonds. Metathesis may occur between two like molecules (often referred to as self-metathesis) and/or it may occur between two different molecules (often referred to as cross-metathesis). Self-metathesis may be represented schematically as shown in Equation I.

R1—CH═CH—R2+R1—CH═CH—R2R1—CH═CH—R1+R2—CH═CH—R2  (I)

wherein R1 and R2 are organic groups.
Cross-metathesis may be represented schematically as shown in Equation II.

R1—CH═CH—R2+R3—CH═CH—R4R1—CH═CH—R3+R1—CH═CH—R4+R2—CH═CH—R3+R2—CH═CH—R4+R1—CH═CH—R1+R2—CH═CH—R2+R3—CH═CH—R3+R4—CH═CH—R4  (II)

wherein R1, R2, R3, and R4 are organic groups.
In recent years, there has been an increased demand for environmentally friendly techniques for manufacturing materials to take the place of materials typically derived from petroleum sources. For example, researchers have been studying the feasibility of manufacturing biofuels, waxes, plastics, and the like, using natural oil feedstocks, such as vegetable and seed-based oils. In one non-limiting example, metathesis catalysts are used to manufacture candle wax, as described in PCT/US2006/000822, which is herein incorporated by reference. Metathesis reactions involving natural oil feedstocks offer promising solutions for today and for the future.
The metathesized natural oil-based compositions may have low melting points that are suitable for use in certain applications, such as candle waxes. However, it would be advantageous to develop higher melting point waxes that utilize the metathesized natural oil as well. Such waxes would have the potential to replace microcrystalline polyethylene or Fisher-Tropsch based waxes. Additionally, higher melting point waxes could used as a structuring agent in cosmetics, emulsifying/thickening agent, slip agent, internal lubricant, pigment dispersant, or a hot melt adhesive, as well as other wax applications.

In some embodiments, a feedstock includes canola or soybean oil, as a non-limiting example, refined, bleached, and deodorized soybean oil (i.e., RBD soybean oil). Soybean oil typically comprises about 95% weight or greater (e.g., 99% weight or greater) triglycerides of fatty acids. Major fatty acids in the polyol esters of soybean oil include saturated fatty acids, as a non-limiting example, palmitic acid (hexadecanoic acid) and stearic acid (octadecanoic acid), and unsaturated fatty acids, as a non-limiting example, oleic acid (9-octadecenoic acid), linoleic acid (9,12-octadecadienoic acid), and linolenic acid (9,12,15-octadecatrienoic acid).
As used herein, the terms “metathesize” and “metathesizing” may refer to the reacting of a feedstock in the presence of a metathesis catalyst to form a metathesized product or “metathesized natural oil” comprising a new olefinic compound.

At that temperature, the wax may be at or close to the solid state, or it may be semisolid, depending on the composition of the wax being tested. The congeal point may be measured using ASTM-D938, incorporated by reference herein.
As used herein, the term “needle penetration” may refer to the relative hardness of the wax sample. The needle penetration may be measured using ASTM-D1321-02a, incorporated by reference herein.
As used herein, the term “peak force” may refer to the relative hardness of the wax sample. In certain embodiments, the peak force measurement is used to measure the relative hardness of a blended wax sample comprising an amidated metathesized natural oil and a natural oil.

A number of valuable amide wax compositions may be prepared by reacting an amine with an ester-functional group of a metathesized natural oil in the presence of a basic catalyst or heat to form an amidated metathesized natural oil. This reaction may generate amidated metathesized natural oil compositions having unique properties over other forms of amide waxes, natural oils, or metathesized natural oils. Such unique properties may include a higher drop point, higher congeal point, leveling effect, improved hardness, improved malleability, improved emulsifiability, improved functionality, improved viscosity, and/or improved compatibility with other materials (such as triglyceride oils and waxes, polyamides, stearic acid, ethylene vinyl acetate copolymers, tackifier resins, and paraffins in low concentration). In certain embodiments, it is possible to tailor the range of certain properties (such as drop point or hardness) by modifying the amount or type of amine used in the reaction with the metathesized natural oil.
In certain embodiments, the amidated metathesized natural oil may possess properties equal to or improved over commercial waxes for various applications such as: high temperature lubricants, rheology modifiers, plastic processing applications (e.g., release agents, slip agents, anti-tack agents, nucleation and lubrication for plastics), polymer processing applications, wood/plastic composites, hot melt adhesives, slip agents for paraffin wax coatings, metal working applications, road construction waxes, emulsifying waxes, binders for cosmetics, softening point/hardness modifiers, thickening agents, metal powder (sintering) processing applications, wetting agents, foam stabilizers, polishes, coatings, structurants (i.e., the ability of the wax to partially or fully solidify a mixture of oils), pigment carriers, corrosion inhibitors, or inks/toners.

In certain embodiments, the natural oil in the amidated metathesized natural oil composition has been metathesized in the presence of a metathesis catalyst to form a metathesis oligomer (or “metathesized natural oil”). The metathesis catalyst in this reaction may include any catalyst or catalyst system that catalyzes a metathesis reaction. Any known metathesis catalyst may be used, alone or in combination with one or more additional catalysts. Non-limiting exemplary metathesis catalysts and process conditions are described in PCT/US2008/009635, pp. 18-47, incorporated by reference herein. A number of the metathesis catalysts as shown are manufactured by Materia, Inc. (Pasadena, Calif.).
Metathesis is a catalytic reaction that involves the interchange of alkylidene units among compounds containing one or more double bonds (i.e., olefinic compounds) via the formation and cleavage of the carbon-carbon double bonds. The metathesis reaction of the natural oil feedstock having unsaturated polyol esters results in the oligomerization of the unsaturated polyol ester having a mixture of olefins and esters that may comprise one or more of: metathesis monomers, metathesis dimers, metathesis trimers, metathesis tetramers, metathesis pentamers, and higher order metathesis oligomers (e.g., metathesis hexamers), as shown in FIG. 1. A metathesis dimer refers to a compound formed when two unsaturated polyol ester molecules are covalently bonded to one another by a metathesis reaction. In certain embodiments, the molecular weight of the metathesis dimer is greater than the molecular weight of the individual unsaturated polyol ester molecules from which the dimer is formed. A metathesis trimer refers to a compound formed when three unsaturated polyol ester molecules are covalently bonded together by metathesis reactions. A metathesis trimer may be formed by the cross-metathesis of a metathesis dimer with an unsaturated polyol ester. A metathesis tetramer refers to a compound formed when four unsaturated polyol ester molecules are covalently bonded together by metathesis reactions. A metathesis tetramer may be formed by the cross-metathesis of a metathesis trimer with an unsaturated polyol ester. Metathesis tetramers may also be formed, for example, by the cross-metathesis of two metathesis dimers. Higher order metathesis oligomers (such as metathesis pentamers and metathesis hexamers) may also be formed.
In certain embodiments, the metathesized natural oil in the amidated metathesized natural oil composition is derived from vegetable oil, algal oil, animal fat, tall oil, derivatives of these oils, or mixtures thereof. Representative non-limiting examples of vegetable oils include canola oil, rapeseed oil, coconut oil, corn oil, cottonseed oil, olive oil, palm oil, peanut oil, safflower oil, sesame oil, soybean oil, sunflower oil, linseed oil, palm kernel oil, tung oil, jatropha oil, mustard oil, camelina oil, pennycress oil, and castor oil.

Representative non-limiting examples of natural oil derivatives include metathesis oligomers, gums, phospholipids, soapstock, acidulated soapstock, distillate or distillate sludge, fatty acids and fatty acid alkyl ester (e.g. non-limiting examples such as 2-ethylhexyl ester), hydroxy substituted variations thereof of the natural oil. For example, the natural oil derivative may be a fatty acid methyl ester (“FAME”) derived from the glyceride of the natural oil. In some embodiments, a natural oil feedstock includes canola or soybean oil, as a non-limiting example, refined, bleached, and deodorized soybean oil (i.e., RBD soybean oil). Soybean oil typically comprises about 95% weight or greater (e.g., 99% weight or greater) triglycerides of fatty acids. Major fatty acids in the polyol esters of soybean oil include saturated fatty acids, as a non-limiting example, palmitic acid (hexadecanoic acid) and stearic acid (octadecanoic acid), and unsaturated fatty acids, as a non-limiting example, oleic acid (9-octadecenoic acid), linoleic acid (9,12-octadecadienoic acid), and linolenic acid (9,12,15-octadecatrienoic acid).

In one embodiment, the drop point of the natural oil composition is increased by at least 5° C. by the addition of less than approximately 1 percent by weight amidated metathesized natural oil to the natural oil composition. In another embodiment, the drop point of the natural oil composition is increased by at least 50° C. by the addition of less than approximately 10 percent by weight amidated metathesized natural oil to the natural oil composition.
In other embodiments, the drop point of the amidated metathesized natural oil-natural oil blend is greater than the drop point of an amide wax derived from a fatty acid and amine reaction. In some embodiments, the amide wax-natural oil blend comprises approximately 0.01 percent by weight, 0.1 percent by weight, 0.5 percent by weight, 1 percent by weight, 2 percent by weight, 5 percent by weight, 10 percent by weight, or 20 percent by weight amide wax in the blend, and has a drop point that is at least 5° C., 10° C., 20° C., 30° C., 40° C., or 50° C. greater than the drop point of the amide wax derived from a fatty acid-amine reaction (e.g., ethylene bis stearamide formed from stearic acid and ethylenediamine).
In certain embodiments, the amidated metathesized natural oil is blended with a natural oil or natural oil derivative composition to increase the congeal point of the natural oil composition. Increasing the congeal point of the natural oil composition may be beneficial for various commercial embodiments such as hot melt adhesives. In one embodiment, the congeal point of the natural oil composition is increased by at least 5° C., 10° C., 20° C., 30° C., 40° C., or 50° C. by the addition of approximately 0.01 percent by weight, 0.1 percent by weight, 0.5 percent by weight, 1 percent by weight, 2 percent by weight, 5 percent by weight, 10 percent by weight, or 20 percent by weight amidated metathesized natural oil to the natural oil composition. In one embodiment, the congeal point of the natural oil composition is increased by at least 5° C. by the addition of less than approximately 0.5 percent by weight amidated metathesized natural oil to the natural oil composition. In another embodiment, the congeal point of the natural oil composition is increased by at least 50° C. by the addition of less than approximately 5 percent by weight amidated metathesized natural oil to the natural oil composition.
In other embodiments, the congeal point of the amidated metathesized natural oil-natural oil blend is greater than the congeal point of an amide wax derived from a fatty acid and amine reaction. In some embodiments, the amidated metathesized natural oil-natural oil blend comprises approximately 0.01 percent by weight, 0.1 percent by weight, 0.5 percent by weight, 1 percent by weight, 2 percent by weight, 5 percent by weight, 10 percent by weight, or 20 percent by weight amidated metathesized natural oil in the blend, and has a congeal point that is at least 5° C., 10° C., 20° C., 30° C., 40° C., or 50° C. greater than the congeal point of the amide wax derived from a fatty acid-amine reaction.
While the invention as described may have modifications and alternative forms, various embodiments thereof have been described in detail. It should be understood, however, that the description herein of these various embodiments is not intended to limit the invention, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the claims.

EXAMPLES
Example 1
70 grams of hydrogenated metathesized soybean oil (HMSBO) were melted and filled into a reactor under nitrogen gas. Next, 7.17 grams of ethylenediamine (i.e., a 2:3 ratio of amine equivalents in the amine to ester equivalents in the metathesized natural oil) were added under nitrogen at approximately 60° C. The mixture was stirred/homogenized for a few minutes and 0.35 grams of lithium carbonate basic catalyst were added (i.e., 0.5 percent by weight catalyst per HMSBO). The mixture was stirred and heated to 120-180° C. under nitrogen and held at 120-180° C. for several hours. After the reaction, the mixture was vacuum pumped for 30-60 minutes to drive off the water, unreacted amine, and glycerol.

Tables 1A and 1B show the results for drop point using the Mettler Drop Point FP80 system, congeal point using ASTM-D938, and needle penetration using ASTM-D1321-02a.
The majority of the HMSBO waxes in Table 1A had drop points greater than 150° C. (300° F.) with the exception of the amidated metathesized natural oil produced from ethanolamine. Ethanolamine forms esters in competition with amides. The ethylenediamine reaction produced the lowest needle penetration value (i.e., the hardest wax, similar to carnauba wax), which may be attributed to its diamide structure where both amine groups are close to each other (amide groups show strong interactions like the ones in structural proteins). The HMSBO reaction with ethanolamine and diethylamine produced waxes having hardness (19 dmm, 18 dmm) similar to beeswax. The highest drop point was observed with the diethylamine reaction caused by high viscosity.
In comparison, the amidation of non-metathesized soybean oil (S-155) had a drop point around 106° C., as shown in Table 1B.
Amidation of hydrogenated metathesized natural oils such as HMSBO appears to be an optimal route to achieve high melting point waxes that are improvements over the metathesized natural oil itself or a typical fatty acid amide having no poly-functional properties. Starting from the hydrogenated metathesized natural oil, the amidated metathesized natural oil product can be obtained in a one-pot reaction. Additionally, there is little to no waste or byproduct besides the replaced free glycerol (which can be removed to achieve increased drop point temperatures and increased hardness). Additional reduction of the paraffin content improves the hardness of the material due to the plasticizing effect of the paraffin.
Example 5
70 grams of fatty acid methyl ester derived from hydrogenated metathesized soybean oil were melted and filled into a reactor under nitrogen gas. Next, 7.17 grams of ethylenediamine (i.e., a 2:3 ratio of amine equivalents in the amine to ester equivalents in the FAME) were added under nitrogen at approximately 60° C. The mixture was stirred/homogenized for a few minutes and 0.35 grams of lithium carbonate basic catalyst were added (i.e., 0.5 percent by weight catalyst per FAME). The mixture was stirred and heated to 120-180° C. under nitrogen and held at 120-180° C. for several hours. After the reaction, the mixture was vacuum pumped for 30-60 minutes to drive off the water and unreacted amine. Finally, the resulting wax was decanted out of the flask and tested for physical properties such as drop point, congeal point, and needle penetration (shown below in Table 2).

The mixture was stirred/homogenized for a few minutes and 0.35 grams of lithium carbonate basic catalyst were added (i.e., 0.5 percent by weight catalyst per FAME). The mixture was stirred and heated to 120-180° C. under nitrogen and held at 120-180° C. for several hours. After the reaction, the mixture was vacuum pumped for 30-60 minutes to drive off the water and unreacted amine.

Table 2 shows the results for drop point using the Mettler Drop Point FP80 system, congeal point using ASTM-D938, and needle penetration using ASTM-D1321-02a.
Comparing the physical properties of the waxes in Tables 1 and 2, amidation of hydrogenated metathesized soybean oil produced more waxes with higher drop points than the amidation of the fatty acid methyl esters having no poly-functional properties. Structure and amino group concentration also play a part in the physical properties of the amidated metathesized natural oils produced. For example, diethylamine (a secondary amine consisting of an amino group with two ethyl group substituents) reacted with the HMSBO to produce a wax with a higher drop point and congeal point than the FAME.
Example 9
Fatty Acid-Amidated Metathesized Natural Oil Blend Study
In this example, HMSBO fatty acid waxes were blended with various concentrations of amidated metathesized natural oil (20 percent by weight amidated metathesized natural oil, 40 percent by weight, 60 percent by weight, and 80 percent by weight). The physical properties of each blend were studied to determine the effects of the amidated metathesized natural oil on the blend. Additional samples of 100% fatty acid wax (i.e., 0 percent by weight amidated metathesized natural oil) and 100% amidated metathesized natural oil were studied as well.
The amidated metathesized natural oil was prepared by adding 700 g HMSBO to a reactor equipped with a stirrer (heavy magnetic stir bar). The HMSBO was stirred and heated in the reactor to 80° C. under nitrogen gas. Next, 72 g ethylenediamine was added to the reactor and stirred/homogenized for a few minutes. Then, 3.5 g sodium carbonate basic catalyst was added as a powder. The mixture was stirred vigorously to keep the catalyst agitated. The reactor was heated to 120° C. and then to 150° C. After 20-30 minutes, the product began to solidify. Therefore, the reactor temperature was increased again to 165° C. to keep the product liquid. The reaction time was at least one hour at elevated temperature (i.e., greater than 140° C.). After the reaction, the mixture was vacuum pumped for at least 30-60 minutes to drive off the water, unreacted amine, and glycerol.
The blends were made by melting the two waxes together at approximately 170° C. Each blend was stirred until it was clear. Each blend, along with the pure samples of amidated metathesized natural oil and HMSBO fatty acid, was tested for drop point (using the Mettler Drop Point FP80 system) and needle penetration (using ASTM-D1321-02a). The results are shown in FIGS. 4 and 5.
In FIG. 4, the drop point graph shows that the addition of the amidated metathesized natural oil increased the drop point compared to the pure HMSBO fatty acid wax. The trend is an increasing drop point up to 60 percent by weight concentration where there is a slight decrease until it gets to 100 percent by weight (pure amidated metathesized natural oil). This effect could be due to some free amino groups present, which give salt-like interactions with carboxylic groups of the HMSBO fatty acids. The highest drop point of 172.3° C. (342.1° F.) was achieved at 40 percent by weight amidated metathesized natural oil, but even at 20 percent by weight amidated metathesized natural oil, there was an increase of about 22° C. (40° F.) from the pure HMSBO fatty acid.
FIG. 5 shows the needle penetration values with increasing amidated metathesized natural oil concentration. The pure distilled fatty acid has a value of 1.5 dmm and the pure amidated metathesized natural oil has a value of 10 dmm. The trend leans toward a softer wax as the amidated metathesized natural oil concentration increases. The optimum penetration value (i.e., hardest wax) of 1 dmm resulted with the 40 percent by weight amidated metathesized natural oil concentration sample.
The results of this study prove that drop point of the pure distilled fatty acid can be manipulated with the addition of the amidated metathesized natural oil. The physical product of a few of the blends (e.g., the 40 percent by weight amidated metathesized natural oil concentration blend) has the shrinkage properties and hardness similar to that of a carnauba or montan wax. The shine or glossiness is another added quality. The optimal blend was observed at 40 percent by weight amidated metathesized natural oil concentration using this particular amidated metathesized natural oil and fatty acid blend. Other amidated metathesized natural oils may also be utilized for blending with the distilled fatty acid.
Example 10
S155-Amidated Metathesized Natural Oil Blend Study
S-155 is a hydrogenated soybean oil sold by Elevance Renewable Sciences, Bolingbrook, Ill. S-155 has potential for use in hot melt adhesive applications. However, the congeal point for the wax is too low by approximately 6° C. (10° F.). In this example, S-155 hydrogenated soybean oil was blended with various concentrations of amidated metathesized natural oil (0.05 percent by weight amidated metathesized natural oil, 0.1 percent by weight, 0.3 percent by weight, 0.5 percent by weight, 1 percent by weight, 2 percent by weight, 3 percent by weight, and 5 percent by weight). The physical properties of each blend were studied to determine the effects of the amidated metathesized natural oil on the blend. Additional samples of 100% S-155 (i.e., 0 percent by weight amidated metathesized natural oil) were studied as well. The amidated metathesized natural oil was prepared according to Example 9. The blends were made by stirring the two waxes together and heating the blend to approximately 170-200° C. It was observed that the resulting blends for the higher concentrations of amidated metathesized natural oil turned into a petroleum-like consistency upon cooling. Each blend, along with the pure samples of S-155, was tested for congeal point (using ASTM-D938) and drop point (using the Mettler Drop Point FP80 system). The results are shown in FIGS. 6 and 7.
In FIG. 6, the congeal point graph shows that the addition of the amidated metathesized natural oil increased the congeal point compared to the pure S-155 hydrogenated soybean oil. With only a 1 percent by weight concentration of amidated metathesized natural oil, the congeal point more than doubled from 52° C. (126° F.) to 129° C. (264.2° F.) and further increased with higher concentrations of amidated metathesized natural oil.
During cooling, the clear melt turned cloudy. This effect increases for higher concentrations. This effect is due to crystallization of the higher melting amidated metathesized natural oil in S-155. These crystallites act as nucleation sites for the S-155 and cause the congeal point to increase. For concentrations below 1 percent by weight amidated metathesized natural oil, the rate at which the congeal point increases gradually. Above 1 percent by weight amidated metathesized natural oil, the change is more abrupt.
Similarly, in FIG. 7, the drop points for lower concentrations of amidated metathesized natural oil (<1 percent by weight) in the wax blend were between 62.3° C. (144.2° F.) and 67.4° C. (153.4° F.). At 1 percent by weight amidated metathesized natural oil concentration and greater, the observed increase in drop point was almost linear. It appeared that the addition of the amidated metathesized natural oil improved some of the brittleness of S-155 without softening it.
The results of this study prove that the congeal point of the pure S-155 can be successfully manipulated with the addition of the amidated metathesized natural oil. An increase in the congeal point by 6° C. (10° F.) in relation to pure S-155 could be achieved with the addition of approximately 0.15-0.20 percent by weight of this particular amidated metathesized natural oil.
Example 11
Additional Amide Wax Blends
Comparable studies were performed with other low melting waxes such as paraffin to observe the increase in the drop point of these materials. The blending of a small amount of amidated metathesized natural oil (produced by reacting ethylenediamine with HMSBO) with natural oils [HMSBO, stearic acid, paraffin, Stable Flake® P oil (a hydrogenated palm oil available from Cargill, Inc., Minneapolis, Minn.)] gives petrolatum-like materials.

It was observed that the drop point of the amidated metathesized natural oil-natural oil blends increased from 66° C. to 183° C. with the addition of 5 percent by weight amidated metathesized natural oil in the HMSBO. A mere 2 percent by weight addition of amidated metathesized natural oil in HMSBO nearly doubled the drop point from 66° C. to 119° C. Additionally, the addition of amidated metathesized natural oil in Stable Flake® P increased the drop point from 57° C. to 83° C. (2 percent by weight addition) and 151° C. (5 percent by weight addition). Further, the addition of amidated metathesized natural oil in paraffin increased the drop point from 55° C. to 103 (1 percent by weight addition) and 146° C. (2 percent by weight addition).
Example 12
Physical Property/Time Dependency study
In this example, amidated metathesized natural oils were prepared by reacting ethylenediamine with HMSBO. The reaction time was varied (1 hr, 2 hr, 4 hr, and 6 hr) and the resulting wax products were analyzed.
For each reaction, approximately 50 g HMSBO was added to a reactor flask and placed in an oil bath heated to 100° C. to melt the wax. Nitrogen gas was flushed through the apparatus as the wax was melted. Next, approximately 5.1 g ethylenediamine was added to the reactor and stirred/homogenized for 5 minutes. Then, 0.25 g lithium carbonate basic catalyst was added. The mixture was stirred to agitate the catalyst. The reactor was then heated to approximately 170° C. and held for 1, 2, 4, or 6 hours. After the reaction, the mixture was vacuum pumped for an hour to drive off the water, unreacted amine, and glycerol. Each wax was then tested for physical properties such as drop point (using the Mettler Drop Point FP80 system) and needle penetration value (using ASTM-D1321-02a). The results of the tests are shown in FIGS. 8 and 9.
In FIG. 8, the drop point data shows a slight increase in going from 1 hr to 2 hr. The remaining data is steadier with another slight increase at the 6 hr sample. Therefore, it would be up to the user to choose the appropriate reaction time according to efficiency, production, and cost-effectiveness.
In FIG. 9, the needle penetration data show a hardness range from 4-8 dmm, which is harder than the penetration values for most typical commercial waxes (e.g., 1-4 dmm for hydrogenated natural oils, microcrystalline waxes and natural waxes such as beeswax). The 1 hr and 6 hr samples showed some cracking on the sides. The 4 hr sample was deemed the hardest and showed more glossiness than the other samples. This could be due to its crystal structure that also gives it its hardness. All samples showed the same bilateral shrinkage that carnauba wax displays.
In conclusion, the amine-metathesized natural oil reaction can be done in 1 hr and still achieve a high melting point wax. The addition of an hour or two may further improve wax hardness and increase drop point. In certain embodiments, the reaction time of four hours may provide more optimal properties. However, if the range of drop points achieved is appropriate for the potential application, then a 1 hr reaction setup could consume less time and be more cost-effective.
Example 13
In this example, amidated metathesized natural oils were prepared by reacting ethylenediamine with metathesized soybean oil (MSBO) that has not been hydrogenated. The amidated metathesized natural oil was prepared by adding 70 g MSBO to a reactor, wherein the MSBO was stirred and heated in the reactor to 80° C. under nitrogen gas. Next, 14 g ethylenediamine was added to the reactor and stirred/homogenized for a few minutes. Then, 0.35 g sodium carbonate basic catalyst was added as a powder. The mixture was stirred vigorously to keep the catalyst agitated. The reactor was heated to 170° C. and held at temperature for 4 hours. After the reaction, the mixture was vacuum pumped for at least 30-60 minutes to drive off the water, unreacted amine, and glycerol. Finally, the resulting wax tested for physical properties such as drop point and needle penetration (shown below in Table 3).
Example 14
In this example, amidated metathesized natural oils were prepared by reacting ethanolamine with metathesized soybean oil (MSBO). The amidated metathesized natural oil was prepared by adding 70 g MSBO to a reactor, wherein the MSBO was stirred and heated in the reactor to 80° C. under nitrogen gas. Next, 20 g ethanolamine was added to the reactor and stirred/homogenized for a few minutes. Then, 0.35 g sodium carbonate basic catalyst was added as a powder. The mixture was stirred vigorously to keep the catalyst agitated. The reactor was heated to 170° C. and held at temperature for 4 hours. After the reaction, the mixture was vacuum pumped for at least 30-60 minutes to drive off the water, unreacted amine, and glycerol. Finally, the resulting wax tested for physical properties such as drop point and needle penetration (shown below in Table 3).

Table 3 shows the results for drop point using the Mettler Drop Point FP80 system and needle penetration using ASTM-D1321-02a. The waxes have comparably high drop points with high penetration values, offering a new kind of material compared to currently commercially available waxes.
Additionally, comparing the physical properties of the amidated metathesized natural oils created from MSBO versus the amidated metathesized natural oils in Tables 1 and 2, amidation of MSBO produced softer waxes than the amide waxes from HMSBO and FAME.
Example 15
In this example, four amidated metathesized natural oil samples were prepared by reacting ethylenediamine with hydrogenated metathesized soybean oil (HMSBO).
For each wax sample, approximately 70 g HMSBO was added to a reactor flask and placed in an oil bath heated to 100° C. to melt the wax. Nitrogen gas was flushed through the apparatus as the wax was melted. Next, approximately 0.43 g ethylenediamine was added to the reactor and stirred/homogenized for a few minutes. Then, approximately 0.35 g sodium carbonate basic catalyst was added. The mixture was stirred to agitate the catalyst and the reactor flask temperature was held at approximately 117° C. for one hour. Then, the temperature was raised to approximately 160-170° C. for 1, 2, 3, and 4 hours for the four samples, respectively.
After the allotted reaction time, the wax product was distilled under vacuum pressure utilizing a trap submerged in liquid nitrogen for one hour at 200° C. Finally, each wax tested for physical properties such as drop point using the Mettler Drop Point FP80 system and needle penetration using ASTM-D1321-02a (shown below in Table 4).

The results from these tests showed that the ethylenediamine reaction with HMSBO could be conducted in as little as one hour to produce a sample that has a drop point approximately 100° C. Additionally, the results showed that the drop point and needle penetration increased slightly based upon the extent of the reaction time from 1 to 3 hours. It is noted that Example 15-4 produced a lower drop point than expected and sandy brown color due to poor pumping/low flow of nitrogen.
Example 16
In this example, three amidated metathesized natural oil samples were prepared by reacting diethanolamine with hydrogenated metathesized soybean oil (HMSBO) in a similar manner to Example 15. However, in this example, the amine was added directly to the flask before the HMSBO was melted.
For each wax sample, approximately 70 g HMSBO was added to a reactor flask with approximately 10 g diethanolamine. The flask was placed in an oil bath and heated to 100° C. to melt the mixture. Nitrogen gas was flushed through the apparatus as the mixture was melted. Then, approximately 0.35 g sodium carbonate basic catalyst was added. The reactor flask temperature was raised to approximately 190° C. for 12, 14, and 16 hours for the three samples, respectively.
After the allotted reaction time, the wax product was distilled under vacuum pressure utilizing a trap submerged in liquid nitrogen for one hour at 200° C. Finally, the drop point for each wax was tested using the Mettler Drop Point FP80 system (shown below in Table 5).

The results from these tests showed a higher drop point for the 14 hr reaction time, but it also has less of a yield than the 12 and 16 hour reactions. In certain embodiments, the reaction time should be 12 hours or less if a lower drop point is also desired (and possibly higher yield).
Diethanolamine has three groups that can react with the ester functionalities of the HMSBO. The amino group reacts first due to its higher nucleophilic character. The hydroxyl groups need more reaction time and deliver a higher cross-linked product. The DEA-HMSBO samples produced in this example report are in the medium range of drop points/viscosity.

The sunscreen is prepared by combining all of the ingredients in a mixing vessel. The Phase A ingredients are then heated to 70-80° C. to melt the wax. The ingredients are mixed to disperse the wax into the oil. The ingredients for Phase B are combined in a separate container, heated to the same temperature as Phase A, and mixed until a homogenous mixture is obtained. Phase B is then combined with Phase A with turbulent mixing. The mixer speed must be sufficient to rapidly incorporate Phase B into the batch as it is added. The emulsion will thicken as Phase B is added so the mixer speed must be increased during the addition to maintain good agitation. After all of Phase B has been added, the mixing is continued while the batch is cooled to room temperature.
Example 23
A series of simple emulsions were made with the polar amidated metathesized natural oil to illustrate the emulsification and thickening performance with a variety of cosmetic oils. Emulsion formulations intended for skin care applications like hand and body lotions or creams usually contain ingredients (thickeners) to increase the viscosity of the emulsion formulation. Thickeners are necessary to provide the formulation with the texture and consistency that consumers expect for creams and lotions. For example, a lotion should be pourable, but not runny; a cream should be thicker than a lotion with a the consistency of a soft solid. Thickening the formulation provides the additional advantage of improving the stability of the formulation. When comparing thickeners for relative efficacy, a common approach is to add the different thickeners to a simple emulsion formulation and then measure the viscosity of the emulsions. More efficacious thickeners will produce higher emulsion viscosities compared to less efficacious thickeners.
The emulsions were prepared by first heating the water to about 80° C. In a separate mixing vessel, the cosmetic oil and the polar amidated metathesized natural oil were heated to about 70° C. in a hot water bath and mixed using a dual blade mixer (turbine blade at the end of the mixer shaft with a propeller blade mounted 2 cm above). The oil and polar amidated metathesized natural oil were mixed at about 500 rpm while the hot water was slowly added. After all of the water was added, the mixer was stopped and the walls of the mixing vessel were scraped with a metal spatula to remove any material that was not dispersed into the batch. The heating bath was removed and the mixer speed was increased to about 800 rpm. The batch was then mixed for 30 minutes while it cooled.
The viscosity of the emulsion was measured about 24 hours after they were made using a Brookfield viscometer, model RVDVII+ equipped with a helipath stand. A number 93 “T” spindle and a speed setting of 10 rpm were used.

The same procedure was used to prepare these emulsions. These emulsions were stable, but much lower in viscosity compared to the emulsions prepared with the polar amidated metathesized natural oil. It was difficult to measure the viscosity of these emulsions using the same spindle and speed on the Brookfield viscometer. Larger spindles were used (No. 92 or 91) with higher speeds in an attempt to obtain an accurate viscosity reading, but the reported values are estimates.

Comparative Example 23S
A comparative example was made by synthesizing diethanolamine amide wax from S-155. Fully hydrogenated soybean oil (S-155) was mixed with 13.7 wt % diethanolamine (DEA) and heated under nitrogen to 80° C. until molten. Sodium carbonate (0.5 parts by weight compared to the amount of S-155) was added during stirring. The temperature was raised to 160° C. for 16 hours. Volatiles were removed under vacuum. The DEA amide wax had a measured drop point of 59.1° C. (138.3° F.).
After the wax cooled down, emulsions were prepared using a simple single oil formulation consisting of 5% wax, 5% oil, and 90% water (as discussed above in Example 23). The results showed that in this comparative example, the S-155 derived DEA amide wax gave gelatinous curds and did not form a stable emulsion with silicon oil (dimethicone) compared to metathesized DEA wax in Example 23. A second test emulsion made from the DEA S-155 amide wax with caprylic/capric triglyceride gave an emulsion with a viscosity of 8100 cP compared to around 25000 cP for the metathesized equivalent.
This comparative example shows the superior emulsion properties of metathesized versus non-metathesized hydrogenated DEA amide wax.
Example 24
Pigment Stick
When dispersed into cosmetic oils, the amidated metathesized natural oil may provide a structuring effect. Structurants may be used to make products such as lipsticks or antiperspirant sticks. The structuring performance of amide wax was tested by making the following formulation. Various waxes (“test wax”) were included in the formulation to determine the effect on hardness:

“Test wax”

The waxes were prepared by mixing the first three ingredients in a vessel, heating the mixture to 70-80° C., and gently mixing until the cetearyl alcohol and test wax were melted. In a separate mixing vessel, the pigment blend was dispersed into the cyclopentasiloxane. Then, the pigment dispersion was blended into the hot wax mixture and the heating was maintained to prevent solidification of the wax. As soon as all of the pigment dispersion has been added, the wax was cooled and poured into suitable molds (4 oz wide-mouth glass jar) before the formulation hardened. The wax was allowed to stand for 24 hours before any measurements were taken.
A Texture Analyzer, model TA XT Plus, manufactured by Stable Micro Systems was used to test the hardness of the formulations. This instrument has a movable arm equipped with force sensors that is programmed to push a probe into the sample and record the resistance to penetration as the probe is pushed into the sample. A 45° conical stainless steel probe (TA15) was pushed into the sample at a rate of 0.5 mm/sec to a depth of 10 mm below the surface of the sample. The peak (maximum) force recorded by the instrument was taken as a measure of the hardness of the sample.
The table below gives the hardness results for several test waxes:

Example 25
Lipstick Base
The structuring effect of amide wax was evaluated in a second anhydrous formulation, a lipstick base. A lipstick base is a mixture of oils, waxes, and pigments to which various oil-soluble dyes can be added to produce the desired lipstick color.

Various waxes (“test wax”) were included in the formulation to determine the effect on hardness.

The waxes were prepared by mixing the ingredients for Phase A in a vessel, heating the mixture to 70-80° C., and gently mixing until all of the waxes have melted. In a separate mixing vessel, the ingredients for Phase B were blended using a high shear mixer to fully disperse the pigments. The pigment dispersion (Phase B mixture) was then blended into the hot Phase A mixture and the heat was maintained to prevent solidification of the wax. As soon as all of Phase B had been added, the combined mixture was stirred until homogeneous. Then, the mixture was cooled, and poured into suitable molds before the formulations hardened.
The hardness of the lipstick base samples was measured in the same fashion as the pigment stick (described in the previous example), but because of the tendency of the lipstick base to crack, the penetration depth was reduced to 5 mm. This produces lower peak force measurements compared to the pigment stick, but still allows the structuring effect produced by different waxes to be compared.

Leveling Agent for Anticorrosion Application
In this example, the amidated metathesized natural oil composition produced by reacting ethylene diamine (EDA) with HMSBO can be powderized and used as a leveling agent. In this example, the powderized amide wax was used as a leveling agent in a wax coating (Ca soaps of MSBO) for an anticorrosion application. The EDA amide wax was introduced as a fine powder in a 1 wt % loading level. The surface of the coating was improved and small bubbles, which tend to form in the coating during heating, were prevented by the additive.
