1. 10-Hydroxystearic acid, m.p., 79.5-79.8°C, was isolated from natural and ex-perimentary produced adipocere by reversed-phase column chromatography and gas chromatography.
2. The chemical structure of this acid was further reconfirmed as follows: a) the ketostearic acid, prepared from the original monohydroxystearic acid by the oxidation with chromium trioxide, was converted to the oximes, b) the mixed oximes when submitted to the Beckmann reaggangement
yielded the mixed amides, and c) methyl nonanoate, dimethyl sebacate, and n-octyl-amine were identified by gas-liquidchromato-graphy as the hydrolysis products of the amides.
The author wishes to express his appreciation to Dr. J. F. McGhie for supplying synthetic specimen of 10-hydroxystearic acid and to Dr. T. Murachi and Dr. K. Fukushima for measurement of optical rotation and infrared spectra. Elementary analyses were carried out by the Central Microanalysis Laboratory, Institute for Protein Research, Osaka, Japan.
