摘　　要：以大孔型苯乙烯系三丁胺胺化强碱性阴离子交换树脂为催化剂,催化苯乙腈的α-丁基化反应,研究了反应温度、催化剂用量和反应时间等因素对反应产率的影响,并考察了催化剂的重复使用性能。结果表明:在优化条件下,该催化剂催化苯乙腈的α-丁基化反应产率高达88%以上,且催化剂具有良好的重复使用性能。Alpha butylation of phenyl acetonitrile was carried out under the phase transfer catalysis of macroporous crosslinked poly(tributyl p-vinylbenzyl ammonium chloride). Influence of the amount of the catalyst, reaction temperature and reaction time to the yield of α-butyl phenyl acetonitrile was investigated. Reusing performance of the catalyst was examined. The yield of α-butyl phenyl acetonitrile was more than 88% under optimized condition, and the catalyst showed good reusing performance for the title reaction.
