环戊烯水合法制备环戊醇的研究(Ⅱ)＿＿工艺优化

摘要以正丁醇为溶剂，强酸性阳离子交换树脂Amberlyst36为催化剂，环戊烯为原料，采用直接水合法合成环戊醇。通过考察了反应温度、反应时间、助催化剂的种类、n(水)K〗∶n(环戊烯)、催化剂的用量等关键因素对反应的影响，得出适宜的反应条件：以正丁醇为溶剂，在n(环戊烯∶n(水)为1∶4，催化剂Amberlyst36的用量为体系总质量的9%，反应温度150 ℃，反应时间2 h的条件下，得到环戊烯的转化率为12.42%，环戊醇的选择性为95.78%，并在此条件下考察了催化剂的稳定性，结果表明催化剂性能稳定。

Abstract： The preparation of cyclopentanol by direct hydration of cyclopentene was studied with strong acidic cation Amberlyst36 as catalyst and 1-butanol as solvent.The influences of reaction temperature，reaction time，cocatalyst type，the molar ratio of H₂O to cyclopentene and dosage of catalyst were studied.The optimum reaction conditions were obtained：molar ratio of H₂O to cyclopentene was 1∶4，dosage of catalyst was 9% of the total mass，reaction temperature 150 ℃，reaction time 2 h，the conversion of cyclopentene was 12.42%，and the selectivity to cyclopentanol was 95.78%.And in this condition the stability of the catalyst was investigated.The results showed that the catalyst was stable.
