Abstract

Partial esters of polyhydric alcohols, formed by methanolysis of a fatty oil, and reaction of the mixture of glycerol and methyl esters of fatty acid so obtained with added polyhydric alcohol (see Group IV (b)), are reacted with a polycarboxylic acid or anhydride, preferably at 200-300 DEG C., and in presence of an inert gas, to give a resin. In examples: (1) the partial ester as above prepared from dehydrated castor oil and added glycerol is heated with phthalic anhydride; (2) the partial ester from soyabean oil and pentaerythritol is heated with sebacic acid or maleic anhydride; (3) the partial ester from linseed oil and propylene glycol is heated with maleic acid. Other polycarboxylic compounds specified are fumaric acid, azelaic acid, malic acid, ketomalic acid, citric acid, phthalic acid, hemimellitic acid. Alcohols specified are glycocol, pentaerythritol mannitol, propylene glycol.ALSO:Partial esters of polyhydric alcohols and higher fatty acids are made by reacting a substantially neutral fatty oil with at least 6 mols. of methyl alcohol in presence of an esterification catalyst until the ester interchange reaction is substantially completed, and heating the thus-formed mixture of glycerine and fatty acid methyl esters with added polyhydric alcohol while distilling off the methyl alcohol. Fatty oils specified are soyabean, dehydrated castor, tung, oiticaca, linseed, or rapeseed. Catalysts specified include alkali and alkaline earth hydroxides and alcoholates, and certain quaternary ammonium hydroxides. Polyhydric alcohols specified are glycerol, pentaerythritol, mannitol, and propylene glycol. The esters are neutralized before use as, e.g. hydraulic fluids or plasticizers. They may be converted to resins by reaction with a polycarboxylic acid or anhydride (see Group IV (a)). In examples: (1) dehydrated castor oil is reacted with methyl alcohol in presence of caustic soda, and then with added glycerol; (2) soyabean oil is reacted with methyl alcohol in presence of phenyltrimethylammonium hydroxide, and the mixture of glycerol and methyl esters so obtained is reacted with pentaerythritol; (3) linseed oil is reacted with methyl alcohol in presence of sodium methylate, and the resulting mixture with sodium methylate; (4) tung oil is reacted with methyl alcohol in presence of lime, and the resulting mixture is reacted with glycerol.
