Abstract

A lower dialkyl ester of terephthalic acid, viz. an ester of an alcohol containing not more than 4 carbon atoms, is used as one ingredient in the manufacture of oil-modified alkyd resins to produce crystal-clear resins of short oil length and of low acid value. The oil-modified alkyd resins may be made by the "fatty acid," the "fatty-acid fatty-oil" or the "alcoholysis" process, if desired in a solvent such as xylene or white spirit, and reaction, which may be with a catalyst such as sodium p glycerate, potassium carbonate or litharge, continued until no more monohydric alcohol is evolved by reaction of the dialkyl terephthalate or until a suitable viscosity is reached. In examples (1) castor oil, glycerol and litharge are treated under CO2, dimethyl terephthalate added and heating continued to produce a plasticizer suitable for, e.g. etherified urea-formaldehyde lacquers; (2) hydrogenated castor oil, glycerol and sodium glycerate heated and reacted with dimethyl terephthalate, the final heating being under reduced pressure to produce a similar plasticizer; (3) linseed oil, pentaerythritol and glycol are heated and cooled; pentaerythritol, glycol, phthalic anhydride and dimethyl terephthalate are added and reacted to produce a clear resin; (4) linseed oil fatty acids, glycerol and dimethyl terephthalate are reacted; (5) dehydrated castor oil acids, glycerol and dimethyl terephthalate are reacted. The following polyhydric alcohols may be used: ethylene, propylene, butylene, diethylene, and triethylene glycols, glycerol, polyglycerol, sorbitol, mannitol, and pentaerythritol; the following polycarboxylic acids may be used: succinic, glutaric, adipic, sebacic, maleic, fumaric, itaconic, acetylene dicarboxylic, malic, tartaric, citric and phthalic acids or their anhydrides. The fatty oils may be coconut, palm, castor, cotton seed, soya bean, sunflower seed, poppy seed, dehydrated castor, linseed, tung, perilla, oiticica, or the fatty acids derived from the oils.
