【摘要】 本文研究了PrAPO-5分子筛催化氧化α-蒎烯合成马鞭草烯酮。采用水热法制备了PrAPO-5分子筛，通过一系列表征手段研究了PrAPO-5分子筛的结构，并探究了反应温度、反应时间、氧气压力、催化剂用量对α-蒎烯催化氧化合成马鞭草烯酮的影响及催化剂的重复使用性。结果表明，PrAPO-5分子筛为介孔分子筛，具有APO-5的AFI特征衍射峰。在反应温度为100℃、加入1.0g的α-蒎烯、氧气压力为0.7MPa、反应时间为6h的条件下，α-蒎烯的转化率为87.85%，马鞭草烯酮的产率和选择性分别为25.25%和28.74%。PrAPO-5催化剂在连续回收并重复使用5次后，仍保持理想的催化活性和选择性。更多还原

【Abstract】 Verbenon was synthesized from α-pinene oxidation catalyzed by PrAPO-5molecular sieve. The PrAPO-5 molecular sieve was prepared by hydrothermal method.The structure of PrAPO-5 molecular sieve was characterized by a series of characterization means.The effects of reaction temperature, reaction time, oxygen pressure and the catalyst dosage on the catalytic oxidation of α-pinene to verbenone and the reusability of catalyst were discussed.The results showed that PrAPO-5 molecular sieve was a mesoporous molecular sieve with the characteristic AFI diffraction peak of APO-5.Under the conditions of reaction temperature of 100℃,addition of 1.0g α-pinene, oxygen pressure of 0.7MPa and reaction time of 6h, the conversion of α-pinene was 87.85%, and the yield and selectivity of verbenone were 25.25% and 28.74% respectively. Also the PrAPO-5 catalyst maintained the ideal catalytic activity and selectivity after continuous recovery and reuse five times.更多还原
