Abstract

Myristic and behenic acids, hitherto not reported therein, have been shown to be components of the glycerides of Japan “wax” in contrast to the nonexistence of an alleged heneicosanoic acid. Esterfractionation analysis revealed the following composition: myristic acid 1.9 per cent, palmitic acid 67.5 per cent, stearic acid 11.6 per cent, arachidic acid 0.04 per cent, behenic acid 0.01 per cent, unsaturated acids 13.6 per cent, and dicarboxylic acids 5.3 per cent. A preliminary investigation of the latter resulted in the isolation of an acid which by virtue of its melting point and molecular weight has been tentatively characterized as heneicosane dicarboxylic acid (C23). However, final proof of identity must rest upon subsequent synthesis of this acid.
