    • Disclosed herein are compounds of the general formula ##STR1## wherein x and y are integers from 3 to 9, x and y together equal 12, one Z is hydrogen and the other Z is a carboxylic acid group, and R.sub.1 and R.sub.2 are fatty acid groups. A process for introducing approximately one carboxylic acid group per triglyceride molecule in vegetable oils has been developed, and the resulting acid adduct forms soaps with attractive properties. The process comprises first conjugation of the double bonds of the nonconjugated polyunsaturated groups present in the fatty acid ester and elaidinization with a catalyst, such as iodine, and then adduct formation with acrylic acid to form the compounds of the general formula. This process also greatly stabilizes the triglyceride against atmospheric oxidation and polymerization reactions.
    • 本文公开的是通式为“IMAGE”的化合物,其中x和y是3至9的整数,x和y一起等于12,一个Z是氢,另一个Z是羧酸基团,并且R 1和R 2是脂肪酸基团 。 已经开发了在植物油中每个甘油三酯分子引入大约一个羧酸基团的方法,并且所得酸加合物形成具有吸引人的性质的皂。 该方法包括存在于脂肪酸酯中的非共轭多不饱和基团的双键的第一次共轭,并与催化剂(例如碘)进行反萃取,然后与丙烯酸形成加合物,形成通式的化合物。 该方法也大大稳定了甘油三酯对抗大气氧化和聚合反应。
