α-蒎烯水合主产物的分离与提纯

Separation and purification of main products of α-pinene hydration

根据α-蒎烯水合产物中的龙脑、异龙脑和α-松油醇在邻苯二甲酸酐存在下发生酯化、脱水反应的选择性差异，可将三者大部分分离，提高优质龙脑和α-松油醇的得率。．

As a resulf of the difference in the selectivity of esterification and dehydration between borneol, isoborneol and α-terpineol in the presence of phthalis anhydride, they can be mostly separated so that the yield of the purified products is increased.
