摘要： 为了解决蒎酮酸传统合成方法的条件苛刻和反应时间太长等问题,提出用表面活性剂催化氧化α-蒎烯的新方法。主要研究了用十二烷基硫酸钠(以下简称K12)作催化剂对KMnO4氧化α-蒎烯合成蒎酮酸的反应的催化作用,系统探讨了各种反应因素对α-蒎烯氧化反应的影响。研究结果表明:用表面活性剂K12作催化剂对KMnO4氧化α-蒎烯时,具有催化剂用量少(2%)、反应条件温和(30℃)、反应时间短(5.0～5.5h)和蒎酮酸产率较高(>60%)等优点。

Abstract: 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%.

Key words: pinonic acid, α-pinene, heterogeneous reaction
