左旋α－松油醇的制备方法
摘要：
本发明提供一种以含α－蒎烯为主的松节油为原料，以低碳醇或酮为溶剂，采用改性强酸性苯乙烯系阳离子交换树脂为催化剂，通过固定床反应器进行催化水合反应，一步合成左旋α－松油醇的方法，催化剂与α－蒎烯的重量比为1∶1～10，α－蒎烯与水的摩尔比为1∶1.1～2，水与溶剂的摩尔比为1∶0.1～0.9，反应温度为70～100℃，反应时间为5～13小时，α－蒎烯转化率在95％以上，左旋α－松油醇收率在65％以上。
摘要（英）：

The present invention provides one-step levo-alpha-terpineol synthesizing process, in which turpentine oil with alpha-pinene as main component is used as the material, low-carbon alcohol or ketone assolvent and modified strong acid styrene cationic exchange resin as catalyst and the catalytic hydration is completed in a fixed bed reactor. It has catalyst/alpha-pinene weight ratio of 1 to 1-10, alpha-pinene/water molar ratio of 1 to 1.1-2, water/solvent molar ratio of 1 to 0.1-0.9, reaction temperature of 70-100 deg.c, reaction period of 5-13 hr, alpha-pinene converting rate over 95 % and levo-alpha-terpineol yield over 65 %.
