Abstract
1364219 Tertiary hydroxy polybasic acids CHEVRON RESEARCH CO 11 Jan 1973 [6 Nov 1972] 1621/73 Addition to 1363410 Heading C2C A process for producing a tertiary hydroxy polybasic acid represented by the general formula wherein R is an alkyl group of from 1 to 5 carbon atoms, or an alkylene group of from 1 to 4 carbon atoms having a terminal carboxyl group, and R 4 is hydrogen or an alkyl group of from 1 to 5 carbon atoms, providing that when R 4 is hydrogen, R has more than one carbon atom in its alkylene group, comprises oxidizing with nitrogen dioxide and nitric acid an unsaturated compound represented by the general formula wherein R 4 has the meaning hereinbefore defined, R 1 is an alkyl group of from 1 to 5 carbon atoms or an alkylene group of from 2 to 5 carbon atoms having a terminal hydroxy or acyloxy group of 2 to 5 carbon atoms, and R 2 is hydrogen or an acyl group of from 2 to 5 carbon atoms, providing that when R 4 is hydrogen and R 2 is hydrogen or an acyl group, R 1 is an alkyl group or an alkylene group of from 3 to 5 carbon atoms having a terminal hydroxy or acyloxy group, or R 1 and R 2 are joined together to form part of a heterocyclic unsaturated compound having the general formula wherein n is an integer from 2 to 5, providing that when R 4 is hydrogen, n is greater than 2, the oxidation being effected at a temperature in the range from -10 to 120‹ C. and in a nitric acid solution which has a concentration by weight in the range from 30 to 90 %.
