摘要 研究了Salen-Mn配合物催化空气环氧化苯乙烯的反应.考察了溶剂用量、反应温度、时间、催化剂用量以及异丁醛用量对苯乙烯环氧化反应的影响.当反应温度35℃、反应时间8 h、n(异丁醛)/n(苯乙烯)2.5、催化剂的摩尔分数0.35%时,苯乙烯的转化率达到98.3%,环氧苯乙烷的选择性高达85.9%.实验发现,4种烯烃环氧化反应速率由快到慢的顺序为苯乙烯>环己烯>1-辛烯>1-十二烯. The aerobic oxidation of styrene to its epoxide catalysted by Salen-Mn(Ⅲ) complex was studied. Effects of amount of solvent, reaction temperature, reaction time, mole ratios of isobutyradehyde and catalyst to substrate on reaction were obtained. Conversion of styrene reached 98.3% , with a 85.9 % selectivity of epoxide, when reaction was run at 35 ℃ for 8 h with mole ratios of 2.5 and 0.35 % of isobutyradehyde and catalyst to the substrate, respectively. The catalyst was also applied to epoxidation of other olefins. Conversion decreased in the order of styrene, cyclohexene, 1-octene, 1-dodecene.
