Title: Modified alkyd resin compositions and process of preparing the same
IPC: C09D163/00
Filed: 1959-06-12
Abstract: A film-forming alkyd ester composition comprises (1) a monobasic acid-modified alkyd ester which is the reaction product of a monocarboxylic acid, a polyol and a dicarboxylic acid or anhydride, this reaction product having an acid value of 45-90 before being further reacted with a dicarboxylic acid anhydride to form a partial ester of acid number 80-120, (2) an epoxidized unsaturated fatty acid ester containing 6-26 carbon atoms in the fatty acid chains and (3) a volatile neutralizing agent in a proportion sufficient to inhibit reaction between free carboxylic acid groups of the modified alkyd and the epoxy groups of the epoxidized ester.  Specified are monocarboxylic acids numerous unsaturated and saturated fatty acids derived from fatty oils of vegetable, animal and marine origin (the oils themselves may be used reacting by alcoholysis) and benzoic, p-tert. butyl benzoic, 2-ethyl hexoic and pelargonic acids polyols pentaerythritol, trimethylolethane, trimethylolpropane, sorbitol, diethylene glycol, propylene glycol, ethylene glycol, glycerol, 1,2,6-hexanetriol, copolymers of styrene and allyl alcohol and glycol etherified phenols dicarboxylic acids and anhydrides phthalic, tetrahydrophthalic, hexahydrophthalic, tetrachlorophthalic, maleic, chlorendic and succinic anhydrides and isophthalic, terephthalic, adipic and fumaric acids for the initial condensation with tetrachlorophthalic, monochlorophthalic, chlorendic, phthalic, tetrahydrophthalic and hexahydrophthalic anhydrides for the subsequent reaction volatile neutralizing agents triethylamine, dimethyl formamide, diethanolamine, ammonia, dimethylethanolamine, mono-ethanolamine, dipropylamine and diisopropylamine and epoxidized unsaturated fatty acid esters epoxidized unsaturated glyceride oils and synthetic esters and dimer and trimer polymers derived therefrom of which there are particularly mentioned epoxidized linseed, segregated soybean, safflower and fish oils, epoxy-stearyl acetate, epoxy-stearyl epoxy-stearate, butyl epoxy-stearate, octyl epoxy-behenate, methyl di-eposy-stearate, di-(epoxy-lauryl) adipate, propyl tri-epoxy-stearate and allyl epoxy-stearate.  A solvent, e.g. xylene or toluene, is incorporated into the composition during its preparation and usually a small proportion of a secondary solvent, e.g. butanol, mono- or di-butyl ether of ethylene or diethylene glycol or mono- or di-ethyl ether of ethylene or diethylene glycol, is also incorporated.  The composition may be dispersed in water by use of excess of the neutralizer.  A compatible resinous material, e.g. a phenol-formaldehyde or melamine-formaldehyde condensation product, an acrylic emulsion or a natural or synthetic rubber latex such as a butadiene-styrene copolymer, may also be included.  The composition may also be pigmented, e.g. with titanium dioxide. Specification 921,622 is referred to.

Patent GB-845401-A (GB)
Title: Improved process for the production of gases containing hydrogen
Inventor: DENT FREDERICK JAMES
IPC: C01B3/38
Filed: 1955-07-15
Abstract: <FORM:0845401/III/1> In a process for the production of gases consisting mainly of hydrogen and carbon monoxide, a carbonaceous material is reacted at a high temperature, e.g. 1200 DEG C., with steam in the presence of oxygen to maintain the reaction temperature and a hydrocarbon in the form of a gas or vapour is reacted at a lower temperature, e.g. 800 DEG -900 DEG C., with steam in the presence of a catalyst, the heat required to maintain the catalytic reaction being supplied by passing the hot gases from the high temperature reaction through a zone arranged in heat exchange relationship with the zone in which the catalytic reaction is carried out.  The gaseous products of the process may be led away as two separate streams or they may be mixed together.  The hydrocarbon for the catalytic reaction may be methane or a methane-rich gas or liquid hydrocarbons of low molecular weight.  The carbonaceous material may be coal or coke or a hydrocarbon such as crude petroleum, a heavy distillate from petroleum or a tar or a gaseous or liquid hydrocarbon similar to that used in the catalytic reaction.  The temperature of the hot gases may be reduced before they reach the heat exchange zone, e.g. by adding gas leaving the catalytic reaction zone.  In the apparatus shown crude petroleum, oxygen and steam are reacted in a chamber 1 at about 1200 DEG C.  The hot gases from the chamber 1 are passed into a vessel 7 containing a bank of tubes 8, through the tubes 8 to an outlet 14.  A catalytic material is arranged in the spaces surrounding the tubes 8 and a mixture of hydrocarbon and steam is admitted at 12, the products of the catalytic reaction being mixed with those from the chamber 1.  Gas may be recycled by the line 15. The carbon monoxide in the gas produced may be reacted with steam to produce carbon dioxide and hydrogen and the carbon dioxide subsequently removed to yield a gas consisting mainly of hydrogen. The steam for this reaction may be introduced with the hydrocarbon in the catalytic reaction zone.
