The constitutional formula of phthioic acid is not the trialkylacetic acid formula presented previously, but is assumed to be 3, 13, 19-trimethvltricosanoic acid formula reported by Polgar and Robinson. An attempt was made to synthesize the acid by the method different from that of Polgar and his co-workers. In order to get the acid by Kolbe's electrolysis of 6-methyldecoic acid (I) and 2, 12-dimethyltridecane-1, 13-dicarboxylic acid monoester (II), 2, 11-dimethyldodecane-1, 12-dicarboxylic acid (III) was synthesized from adipic and sebacic acids, respectively, to determine the synthetic method of (II), and it was found that the yield of the synthesis from sebacic acid was better than that from adipic acid.
