摘　　要：α-甲基苯乙烯是一种基础的化工原料,广泛的应用在乳化剂、农药、合成树脂、合成橡胶的化工生产领域,具有广泛的应用空间,其加氢转化为异丙苯返回主流程氧化制造苯酚、丙酮,从而降低异丙苯单耗,提高苯酚的收率,节约原料费用,降低产品成本。其来源主要分为两种,一是从异丙苯氧化制苯酚、丙酮的副产物中回收;二是由异丙苯脱氢制造。研究温度、反应压力、氢气放空速率等对AMS转化率的影响,通过实验研究表明:温度、反应压力对催化的活性有影响,氢气放空速率对催化活性没有影响。α-methylstyrene is a basic chemical raw material,widely used in emulsifier,pesticide,synthetic resin,synthetic rubber chemical production field,with a wide range of application space,its hydrogenation into isopropylbenzene return to the main process of oxidation to produce phenol,acetone,so as to reduce isopropylbenzene consumption,increase the yield of phenol,save raw material costs,reduce product costs.Its sources are mainly divided into two kinds,one is from the oxidation of isopropylbenzene to phenol,acetone by-product recovery;The second is made of isopropylbenzene dehydrogenation.In this paper,the effects of temperature,reaction pressure and hydrogen venting rate on AMS conversion were studied.The experimental results showed that temperature and reaction pressure had an effect on catalytic activity,while hydrogen venting rate had no effect on catalytic activity.
