Abstract
Existing standard procedures for the microdetermination of C-methyl groups in organic compounds have been discussed, and a modified micromethod, in which the oxidation of the sample and the distillation of the resulting acetic acid are carried out simultaneously, has been presented. New and useful information on the stability of acetic acid, when heated in presence of chromic-sulphuric acid mixture of varying strengths, for periods ranging between 15–90 minutes, and at temperatures varying between 130–300° C, has been given. A number of simple organic substances have been analysed for their C-methyl values by the different procedures, and the results have been recorded and discussed.
