(1) The author synthesized 3, 13, 19-trimethyltricosanoic acid which is the most probable formula of phthioic acid present in tubercle bacilli.
(2) The method of synthesis which was taken by the author, the electrolytic condensation of 6-methyldecoic acid and monoester of 2, 12-dimethyltridecane-1, 13-dicarboxylic acid, is more convenient than that of Polgar and Robinson.
(3) The acid synthesized has the following physical constants: b.p.0.1 205-208°; nD171.4600. The amide melted at 43-44°.
(4) The author obtained a new derivative, p-bromophenacyl ester, melting at 97-98°.
