氢型丝光沸石催化β─蒎烯高选择性水合反应的研究

Study on catalytic high-selective; hydration of β-pinene in the presence of H-Mordenite

本文研究了季铵盐辅助氢型丝光沸石催化β-蒎烯选择性水合反应，季铵盐的结构及用量对该反应生成单环产物的选择性具有显著的影响。选择适当的季铵盐，通过该水合反应一步合成得到α-松油醇，产率53．6％，并且产物的光学活性能够得到较好的保持。

Catalytic highly-selective hydration of P-pinene in the presence of H-Mordenite and quaternary ammonium salts was studied in this paper, the different quaternary ammonium salts and their quantities have a remarkable influence for this reaction on the selectivity for the monocyclic products. Optically active ater pineol was synthesized in one step under the condition, the GC yie1d was 53. 6%, and the ratio of e. e. of α-tepineol to that of β-pinene was 91%.
