Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This is a divisional application of U.S. Ser. No. 16/554,972, filed Aug. 29, 2019, which claims priority under 35 U.S.C. § 119 to provisional application Ser. No. 62/834,627, filed Apr. 16, 2019, both of which are herein incorporated by reference in their entirety. 
    
    
     FIELD OF THE INVENTION 
     The present disclosure relates generally to the field of corrosion control in a water system, especially upstream oil and gas production fluids, using one or more multiple charged compounds derived from polyamines. In particular, the present disclosure relates to using a corrosion control composition comprising one or more modified polyamines that comprise one or more nonionic groups or both cationic and nonionic groups attached to its nitrogen atoms in a water system, especially in a water system for oil and gas operation. The methods and corrosion control compositions disclosed herein are effective to prevent corrosion in a water system. 
     BACKGROUND OF THE INVENTION 
     A water system, including an industrial water system in oil and gas operation, serves many different purposes. Any water system, including its equipment and water, is prone to microbial contamination and fouling. Metal surfaces in any water system are prone to corrosion, partly due to microbial contamination and fouling. 
     Corrosion inhibitors are often added into a water system to protect its metal surface infrastructure, such as carbon steel pipelines, from corrosion. As an example, corrosion inhibitors are often added into upstream oil and gas production fluids to protect carbon steel pipelines and infrastructure from corrosion. Quaternary ammonium compounds have been used for many years as corrosion inhibitors and fouling control agents for a water system. 
     Quaternary ammonium compounds belong to an important subcategory of surfactants because they have unique properties. A main distinction between quaternary ammonium compounds from other surfactants is their unique structures. Quaternary ammonium compounds consist mainly of two moieties, a hydrophobic group, e.g., long alkyl group, and a quaternary ammonium salt group. The unique positive charge of the ammonium plays a key role, e.g., electrostatic interactions, between the surfactant and surface or different components of biofilms. 
     However, the quaternary ammonium compounds used for such purpose are often bis quaternary species or species quaternized with benzyl chloride that are known to be very hazardous. In additional, governmental regulations exist to release any water containing single quaternary compounds into environment. Therefore, there is a continuing need for different or alternative quaternary ammonium compounds that are better and safer corrosion control agents. 
     Accordingly, it is an objective of the present disclosure to develop novel corrosion control agents having improved corrosion control properties. 
     It is a further objective of the disclosure to develop methods and corrosion control compositions to make corrosion control in a water system more efficient and effective. 
     These and other objects, advantages and features of the present disclosure will become apparent from the following specification taken in conjunction with the claims set forth herein.

     Alkalinity Source or Base 
     The disclosed methods of preparation and compositions may include using an effective amount of an alkalinity source or base as a catalyst or ingredient. The alkalinity source or base in turn comprises one or more alkaline compounds. The alkalinity source can be added to the reaction mixture in the form of solid, liquid, or solution thereof. 
     In general, an effective amount of the alkalinity source should be considered as an amount that provides a reaction mixture having a pH of at least about 8. When the solution has a pH of between about 8 and about 10, it can be considered mildly alkaline, and when the pH is greater than about 12, the solution can be considered caustic. 
     The alkalinity source can include an alkali metal carbonate, an alkali metal hydroxide, alkaline metal silicate, alkaline metal metasilicate, or a mixture thereof. Suitable metal carbonates that can be used include, for example, sodium or potassium carbonate, bicarbonate, sesquicarbonate, or a mixture thereof. Suitable alkali metal hydroxides that can be used include, for example, sodium, lithium, or potassium hydroxide. Examples of useful alkaline metal silicates include sodium or potassium silicate (with M 2 O:SiO 2  ratio of 2.4 to 5:1, M representing an alkali metal) or metasilicate. A metasilicate can be made by mixing a hydroxide and silicate. The alkalinity source may also include a metal borate such as sodium or potassium borate, and the like. 
     The alkalinity source may also include ethanolamines, urea sulfate, amines, amine salts, and quaternary ammonium. The simplest cationic amines, amine salts and quaternary ammonium compounds can be schematically drawn thus: 
                         
in which, R represents a long alkyl chain, R′, R″, and R′″ may be either long alkyl chains or smaller alkyl or aryl groups or hydrogen and X represents an anion.
 
     In some embodiments, the methods of preparation are free of the alkalinity source because the reactants contain a primary amine or primary amine group to catalyze the reaction. In some embodiments, the compositions disclosed herein are free of the alkalinity source. 
     Polyamines 
     A polyamine can have, but is not limited to, a generic formula of NH 2 —[R 10′ ] n —NH 2 , (RNH) n —RNH 2 , H 2 N—(RNH) n —RNH 2 , or H 2 N—(RN(R′)) n —RNH 2 , wherein R 10′  is a linear or branched, unsubstituted or substituted C 2 -C 10  alkylene group, or combination thereof; R is —CH 2 —, —CH 2 CH 2 —, —CH 2 CH 2 CH 2 —, —CH(CH 3 )CH 2 —, a linear or branched, unsubstituted or substituted C 4 -C 10  alkylene group, or combination thereof; R′ is —CH 2 —, —CH 2 CH 2 —, —CH 2 CH 2 CH 2 —, —CH(CH 3 )CH 2 —, a linear or branched, unsubstituted or substituted C 4 -C 10  alkyl group, RNH 2 , RNHRNH 2 , or RN(RNH 2 ) 2 ; and n can be from 2 to 1,000,000. The monomer in a polyamine, e.g., the R or R′ group, can be the same or different. In this disclosure, a polyamine refers to both small molecule polyamine when n is from 1 to 9 and polymeric polyamine when n is from 10 to 1,000,000. 
     Small molecule polyamines include, but are not limited to ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine, hexaethyleneheptamine, and tris(2-aminoethyl)amine. 
     Other possible polyamines include JEFFAMINE® monoamines, diamines, and triamines by Huntsman. These highly versatile products contain primary amino groups attached to the end of a polyether backbone normally based on propylene oxide (PO), ethylene oxide (EO), or a mixture of both oxides. JEFFAMINE® amines include a polyetheramine family consisted of monoamines, diamines and triamines based on the core polyether backbone structure. JEFFAMINE® amines also include high-conversion, and polytetramethylene glycol (PTMEG) based polyetheramines. These JEFFAMINE® amines have an average molecular weight (M w ) of from about 130 to about 4,000. 
     A polyamine used in this disclosure can be a polyamine derivative or modified polyamine, in which one or more of the NH protons, but not all, in the polyamine is substituted by an unsubstituted or substituted group. For example, an alkyl polyamine that contains one or more alkyl group connected to the nitrogen atom can be used to produce the multiple charge cationic polyamine disclosed herein. In these PEI derivatives, only some of primary NH 2  or secondary NH protons are replaced by other non-proton groups and the remaining NH 2  or NH protons can still react with a Michael acceptor, such as an activated olefin containing a hydrophilic (ionic) group, by an aza-Michael Addition reaction. 
     One class of the polymeric polyamine includes polyethyleneimine (PEI) and its derivatives. Polyethyleneimine (PEI) or polyaziridine is a polymer with a repeating unit of CH 2 CH 2 NH and has a general formulation of NH 2 (CH 2 CH 2 NH) n —CH 2 CH 2 NH 2 , wherein n can be from 2 to 105. The repeating monomer in PEI has a molecular weight (M w ) of 43.07 and a nitrogen to carbon ratio of 1:2. 
     PEI derivatives include ethoxylated/propylated PEIs, polyquats PEI, polyglycerol quats PEI, and other PEI derivatives, salts, or mixtures thereof. The molar mass of the polyethyleneimines, including modified polyethyleneimines can vary from about 800 g/mol to about 2,000,000 g/mol. For Example, SOKALAN® HP20 is an alkoxylated PEI product. In these PEI derivatives, only some of primary NH 2  or secondary NH protons are replaced by functional groups and the remaining NH 2  or NH protons can still react with a Michael acceptor, e.g., activated olefin or α, β-unsaturated compound containing a hydrophilic (ionic) group. 
     PEIs and their derivatives can linear, branched, or dendric. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups. Totally branched, dendrimeric forms also exist and contain primary and tertiary amino groups. Drawings for unmodified linear, branched, and dendrimeric PEI are shown below. 
     
       
         
         
             
             
         
       
     
     PEI derivatives are usually obtained by substituting proton(s) on the nitrogen atoms with different group. One such PEI derivative is ethoxylated and propoxylated PEI, wherein the polyethyleneimines are derivatized with ethylene oxide (EO) and/or propylene oxide (PO) side chains. Ethoxylation of PEIs can increase the solubility of PEIs. 
     PEI is produced on industrial scale. Various commercial polyethyleneimines are available, including for example those sold under the tradename Lupasol® (BASF), including for example Lupasol® FG, Lupasol® G, Lupasol® PR 8515, Lupasol® WF, Lupasol® G 20/35/100, Lupasol® HF, Lupasol® P, Lupasol® PS, Lupasol® PO 100, Lupasol® PN 50/60, and Lupasol® SK. These PEIs have average molecular weights (M w ) of about 800, about 1,300, about 2,000, about 5,000, about 25,000, about 1,300/2,000/5,000, about 25,000, about 750,000, about 750,000, about 1,000,000, and about 2,000,000, respectively. 
     Two commonly used averages for molecular weight of a polymer are number average molecular weight (M n ) and weight average molecular weight (M w ). The polydispersity index (D) represents the molecular weight distribution of the polymers. Mn=(Σn i M i )/Σn i , M w =(Σn i M i   2 )/Σn i M i , and D=M w /M n , wherein the index number, i, represents the number of different molecular weights present in the sample and n i  is the total number of moles with the molar mass of M i . For a polymer, M n  and M w  are usually different. For example, a PEI compound can have a M n  of about 10,000 by GPC and M w  of about 25,000 by LS. 
     Light Scattering (LS) can be used to measure M w  of a polymer sample. Another easy way to measure molecular weight of a sample or product is gel permeation chromatography (GPC). GPC is an analytical technique that separates molecules in polymers by size and provides the molecular weight distribution of a material. GPC is also sometimes known as size exclusion chromatography (SEC). This technique is often used for the analysis of polymers for their both M n  and M w . 
     These commercially available and exemplary polyethyleneimines are soluble in water and available as anhydrous polyethyleneimines and/or modified polyethyleneimines provided in aqueous solutions or methoxypropanol (as for Lupasol® PO 100). 
     PEI and its derivatives find many applications usually derived from its polycationic character. Because of the presence of amine groups, PEI can be protonated with acids to form a PEI salt from the surrounding medium resulting in a product that is partially or fully ionized depending on pH. For example, about 73% of PEI is protonated at pH 2, about 50% of PEI is protonated at pH 4, about 33% of PEI is protonated at pH 5, about 25% of PEI is protonated at pH 8 and about 4% of PEI is protonated at pH 10. In general, PEIs can be purchased as their protonated or unprotonated form with and without water. The commercial PEIs at pH 13 have a charge (cationic) density of about 16-17 meq/g (milliequivalents per gram). 
     The counterion of each protonated nitrogen center is balanced with an anion of an acid obtained during neutralization. Examples of protonated PEI salts include, but are not limited to, PEI-hydrochloride salt, PEI-sulfuric acid salt, PEI-nitric acid salt, PEI-acetic acid salt PEI fatty acid salt and the like. In fact, any acid can be used to protonate PEIs resulting in the formation of the corresponding PEI salt compound. 
     Suitable polyethyleneimine useful in the present disclosure may contain a mixture of primary, secondary, and tertiary amine substituents or mixture of different average molecular weights. The mixture of primary, secondary, and tertiary amine substituents may be in any ratio, including for example in the ratio of about 1:1:1 to about 1:2:1 with branching every 3 to 3.5 nitrogen atoms along a chain segment. Alternatively, suitable polyethyleneimine compounds may be primarily one of primary, secondary or tertiary amine substituents. 
     The polyamine that can be used to make the multiple charged cationic disclosed herein can have a wide range of its average molecular weight. Different multiple charged cationic compounds with their characteristic average molecular weights can be produced by selecting different starting small molecule polyamines, polymeric PEIs, or mixture thereof. Controlling the size of polyamines or PEI and extent of modification by the α, β-unsaturated compound and epoxide, one can produce the multiple charged cationic compounds with a similar average molecular weight and multiple cationic charges. Because of this character, one can produce and use different multiple charged cationic compounds for a wider range of applications that are using unmodified polyamine or PEIs. 
     Specifically, the polyamines that can be used to make the modified polyamines disclosed here have an average molecular weight (M w ) of about 60-200, about 100-400, about 100-600, about 600-5,000, about 600-800, about 800-2,000, about 800-5,000, about 100-2,000,000, about 100-25,000, about 600-25,000, about 800-25,000, about 600-750,000, about 800-750,000, about 25,000-750,000, about 750,000-2,000,000, about 100, about 200, about 300, about 400, about 500, about 600, about 700, about 800, about 1,000, about 1,500, about 2,000, about 3,000, about 5,000, about 8,000, about 10,000, about 15,000, about 20,000, about 50,000, about 100,000, about 250,000, about 500,000, about 1,000,000, about 2,000,000, or any value there between. 
     Aza-Michael Addition Reaction and Ring Opening Reaction of Epoxide 
     The multiple charged cationic compounds disclosed herein are derived from an aza-Michael Addition Reaction between a polyamine and Michael acceptor such as an activated olefin and from a ring opening reaction between a polyamine and epoxide. The aza Michael Addition Reaction and the ring opening reaction can happen sequentially or simultaneously. In some embodiments, the reaction products of the aza-Michael Addition reaction are further derived with a ring opening reaction of an epoxide. Alternatively, the multiple charged cationic compounds disclosed herein are derived from a ring opening reaction between a polyamine and epoxide and the products of the ring opening reaction then react with Michael acceptor such as an activated olefin or α, β-unsaturated carbonyl compound containing a hydrophilic (ionic) group through an aza-Michael Addition Reaction between the product. 
     An aliphatic amine group may undergo an aza-Michael Addition reaction when in contact with an unsaturated hydrocarbon moiety (e.g., carbon-carbon double bond) that is in proximity of an electron withdrawing group such as carbonyl, cyano, or nitro group. Specifically, the Michael addition is a reaction between nucleophiles and activated olefin and alkyne functionalities, wherein the nucleophile adds across a carbon-carbon multiple bond that is adjacent to an electron withdrawing and resonance stabilizing activating group, such as a carbonyl group. The Michael addition nucleophile is known as the “Michael donor”, the activated electrophilic olefin is known as the “Michael acceptor”, and reaction product of the two components is known as the “Michael adduct.” Examples of Michael donors include, but are not restricted to, amines, thiols, phosphines, carbanions, and alkoxides. Examples of Michael acceptors include, but are not restricted to, acrylate esters, alkyl methacrylates, acrylonitrile, acrylamides, maleimides, cyanoacrylates and vinyl sulfones, vinyl ketones, nitro ethylenes, α, β-unsaturated aldehydes, vinyl phosphonates, acrylonitrile, vinyl pyridines, azo compounds, beta-keto acetylenes and acetylene esters. 
     As used herein, an “activated olefin” refers to a substituted alkene in which at least one of the double-bond carbons has a conjugated electron withdrawing group. Examples of activated olefins include, but not limited to, α, β-unsaturated carbonyl compounds (such as CH 2 ═CHCO—NH—CH 3 , alkyl-CH═CH—CO-alkyl, CH 2 ═CH 2 C(O)—O—CH 3 ), CH 2 ═CH—COOH, CH 2 ═CH(CH 3 )—COOH, CH 2 ═CH—SO 3 H, and like. 
     Aza-Michael addition reaction can be catalyzed by a strong acid or base. In some cases, some ionic liquids can function both as reaction media and catalyst. The preferred catalyst for the Aza-Michael addition reaction to synthesize the disclosed compounds is a base. Exemplary base catalyst can be hydroxide and amines. Because the reaction to synthesize the disclosed compounds uses a polyamine, the polyamine itself can function as a catalyst for the reaction. In such embodiments, no additional catalyst is necessary, or an additional catalyst is optional. Other preferred catalysts include amidine and guanidine bases. 
     The use of solvent and/or diluent for the reaction is optional. When employed, a wide range of non-acidic solvents are suitable, such as, for example, water, ethers (e.g., tetrahydrofuran (THF)), aromatic hydrocarbons (e.g., toluene and xylene), alcohols (e.g., n-butanol), and the like. A wide range of solvents can be used for the reaction because the synthesis process is relatively insensitive to solvent. 
     Generally, the reaction can be carried out at a temperature over a wide range of temperatures. The reaction temperature can range from about 0° C. to about 150° C., more preferably from about 50° C. to about 80° C. The reaction temperature can be about the same from starting of the reaction to end of the reaction and can be changed from one temperature to another while the reaction is going on. 
     The reaction time for the synthesis of the compounds disclosed herein can vary widely, depending on such factors as the reaction temperature, the efficacy and amount of the catalyst, the presence or absence of diluent (solvent), and the like. The preferred reaction time can be from about 0.5 hours to about 48 hours, from about 1 hour to 40 hours, from about 2 hours to 38 hours, from about 4 hours to about 36 hours, from 6 hours to about 34 hours, from about 8 hours to about 32 hours, from about 10 hours to about 30 hours, from about 12 hours to about 28 hours, from about 14 hours to 26 hours, from about 16 hours to 24 hours, from about 18 hours to 20 hours, from about 1 hour to 8 hours, from 8 hours to 16 hours, from 8 hours to about 24 hours, about 2 hours, about 4 hours, about 6 hours, about 8 hours, about 10 hours, about 14 hours, about 16 hours, about 18 hours, about 24 hours, about 30 hours, about 36 hours, or any values there between. 
     The ring opening reaction of an epoxide with an amine is also known in the prior art. This ring opening reaction can be done at a temperature of from about −20° C. to about 200° C. and in the presence of a catalyst, base, or acid. In some embodiments, the ring opening reaction is done free of a catalyst, base, or acid. In some other embodiments, the ring opening reaction is at a temperature from about 100° C. to about 150° C.; a different temperature for the aza Michael Addition reaction; in the presence of a different catalyst, base, or acid. 
     Both aza Michael addition and ring opening reactions for synthesis of the compounds disclosed can be accomplished when one mole of the polyamine and specified moles (two or more moles) of the activated olefin, the epoxide, and the both, are mixed together for a sufficient of time at a temperature described above. 
     It was found that the Aza-Michael addition and ring opening reaction of an epoxide can be used to synthesize the disclosed compounds without having to use a higher temperature greater than 200° C. and high pressure greater than normal atmosphere pressure and with a high yield (greater than 98%).

Thus, various modifications of the embodiments of the disclosure, in addition to those shown and described herein, will be apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims. 
     Example 1 
     General Scheme to Synthesize Exemplary Compounds 
     A generic synthesis reaction scheme for preparation of some of the multiple charged cationic compounds disclosed herein is  FIG.  4   . In this generic scheme, a linear polyethyleneimine is used as a representative for polyamines. Hydrogens on the nitrogen of the linear polyethyleneimine are replaced by both the cationic groups via aza Michael addition reactions and the hydrophobic groups via epoxide ring-opening reaction. Different compositions can be created by varying amounts of the ionic monomers and hydrophobic alkyl epoxide. 
     In  FIG.  4   , k is a integer of 1-100; X is NH or O; R 2  is H, CH 3 , or an unsubstituted, linear or branched C 2 -C 10  alkyl group; R 3  is absent or an unsubstituted, linear or branched C 1 -C 30  alkylene group; Y is —NR 4 R 5 R 6(+)  or a salt thereof, R 4 , R 5 , and R 6  are independently C 1 -C 10  alkyl group or benzyl group; and R 8  is alkyl, or —(CH 2 ) k —O-alkyl, wherein k is an integer of 1-30. 
     Some of the multiple charged cationic compounds disclosed herein can be prepared by reacting a polyamine with one or more epoxides via epoxide ring-opening reaction alone. For these types of cationic compounds, the multiple cationic charges are resulted from protonation of backbone nitrogen atoms at lower pH. 
     The progression of the reactions can be monitored by ESI-MS and/or NMR spectroscopy for consumption of the cationic monomer and epoxide. The reactions can be stopped at time when about &gt;98% for the monomer and epoxide is consumed. The aqueous or alcoholic solution of the multiple charged cationic compounds can be used “as-is” for the application testing. 
     In the scheme described above, water and/or isopropanol can be used as solvent. However, the use of solvent and/or diluent for the reaction is optional. When employed, a wide range of non-acidic solvents are suitable, such as, for example, acetonitrile, ethers (e.g., tetrahydrofuran (THF)), other alcohols (e.g., methanol, ethanol, n-butanol, glycol, PEG, or a mixture) and the like 
     In the scheme described above, no additional catalyst is necessary. Because the reactions to synthesize the disclosed multiple charged cationic compounds uses a polyamine, the polyamine itself can function as a (base) catalyst for both reactions. However, an additional catalyst is optional. Aza-Michael addition and ring-opening reactions employed for synthesis of the disclosed multiple charged cationic compounds can also be catalyzed by a strong acid or base. 
     In the scheme described above, the reactions can be carried at a temperature of from about 50° C. to about 130° C. However, the reaction temperature can range from about 20° C. to about 150° C., more preferably from about 50° C. to about 100° C. 
     In the scheme described above, synthesis is achieved in a two-step reaction. However, the disclosed multiple charged cationic compounds can be synthesized by one-step, one-pot reaction by tandem Michael addition and ring-opening reaction by reacting a polyamine simultaneously with the ionic monomers and epoxide.

     The compounds 5 and 6 are the products from the reaction of the triethylenepentamine and an epoxide. Post ring-opening reaction acidification is done with either acetic acid or methanesulfonic acid. Different compounds can be generated by varying amount of the polyamine and hydrophobic alkyl epoxide. 
     The control chemistry used for comparison was an imidazoline made from the reaction of tall oil fatty acid (TOFA) with diethylene triamine (DETA) and further salted with acetic acid. This chemistry is known to be often used as oilfield corrosion inhibitors. 
     The efficacy for corrosion control is often measured by corrosion bubble cell tests. The bubble cell test simulates low flow areas where little or no mixing of water and oil occurs. The test was conducted using brine (80% of the brine having 3% sodium chloride and 20% of the brine being a hydrocarbon containing 100% LVT-200 kerosene oil). The brine was placed into kettles and purged with carbon dioxide. The brine was continually purged with carbon dioxide to saturate the brine prior to starting the test. After the test began, the test cell was blanketed with carbon dioxide one hour prior to electrode insertion and through the duration of the test to maintain saturation. The kettles were stirred at 150 revolutions per minute (rpm) for the duration of the test to maintain thermal equilibrium at 80° C. The corrosion rate was measured by Linear Polarization Resistance (LPR) techniques. The working electrode used was carbon steel. The counter and reference electrodes were both Hastelloy. The electrodes were all cleaned and polished prior to testing. 
     Data were collected for three hours before about 4 ppm of each of the tested and control compositions was dosed into its respective cell. Each tested or control composition comprises 10 wt-% of the tested or control compound and 1 wt-% of 2-mercaptoethanol (2ME) as synergist in an organic solvent. The actual concentration of the tested or control compound in each cell was 4 ppm and one of 2ME was 0.4 ppm. Data were collected overnight. 
     The results of the bubble cell test are shown in  FIG.  5    and Table 3, wherein ppm is parts per million, CI is corrosion inhibitor, and mpy is mils per year. 0.4 ppm of 2-mercaptoethanol (2ME) were present with each multiple charged cationic compound or control.  FIG.  5    shows the corrosion rate in mils per year during the bubble test period (18 hour). For the blank sample, no 2-mercaptoethanol (2ME) was added.
