【摘要】 以α-甲基苯乙烯为原料,五氧化二钒/烷基紫精插层化合物为光催化剂,对影响光催化合成苯乙酮的实验条件如:溶剂的影响、催化剂的用量、O2流速等进行了研究。实验结果表明:当催化剂浓度为0.20 g/L,O2流速25 mL/min,反应6 h,α-甲基苯乙烯的转化率可达32%,苯乙酮的选择性为98%,产率为31%。更多还原

【Abstract】 Using α-methyl styrene as raw material and vanadium pentoxide/alkyl viologen intercalation compounds as photo-catalyst,the effect of experimental conditions on acetophenone photocatalytic synthesis,such as the solvent,catalyst usage,O₂ flow rate,etc.was studied.The experimental results showed that when the catalyst concentration was 0.20 g/L,the O₂ flow rate was 25 mL/min and the reaction time was 6 h,α-methyl styrene conversion was close to 32%,and the selectivity and yield of acetophenone was 98% and 31%,respectively.更多还原
