STUDY ON A NEW METHOD FOR SYNTHESIS OF PINONIC ACID

In order to improve the strict conditions and the long reaction time required in the traditional method for preparing pinonic acid,a new method,in which surfactant was used to catalyze the oxidation of α-pinene,was brought forward.Catalytic effects of lauryl sodium sulfate(K12)on the oxidation of α-pinene were studied.Factors affecting the reaction were discussed in detail.The oxidation process at 30℃ for about 5-5.5 h in the presence of K12(2% based on the mass of α-pinene)provides pinonic acid at yield more than 60%.
