抄録

From the discovery of higher dibasic acids in Japan wax, many investigations were carried out about the structure of the glycerides of dibasic acids. However, these investigations were mainly concerned with the separation of dibasic acid glycerides from Japan wax, and no definite conclusion has yet been established whether it would be monomolecular type or bimolecular type.<BR>The purpose of this investigation is determining the structure of higher dibasic acid glycerides synthetically prepared. Synthesis of dibasic acids (C12C22) was carried out according to four different methods and pure C22 dibasic acid was obtained.<BR>The paper chromatography of the dibasic acids has been carried out by the reversed phase method using several kinds of stationaly phases, and a linear relationship was observed between Rf value and the carbon number of the acids.<BR>By applying this analytical method to the dibasic acid which was separated from Japan wax according to the Tsujimoto's method, it was found that arachidinic acid was also present besides C20 and C22 acids which were previously known, and the ratio of those three acids was determined by molecular distillation.
