铁掺杂γ-Al2O3分子筛催化苯直接羟基化制备苯酚反应

摘要

通过浸渍法制备了Fe/γ-Al2 O3系列催化剂，研究了不同的煅烧温度和时间对催化剂催化活性的影响。考察了在不同的反应条件（例如：不同的溶剂，反应时间，催化剂的量， H2 O2的量）下催化剂对苯直接羟基化制备苯酚的催化活性，以期得到最优的反应条件。%Fe supported on γ-Al2 O3 catalysts was prepared by impregnation method.The catalytic performances of Fe/γ-Al2 O3 prepared were investigated by various calcined temperature and time.Various reaction parameters , such as different solvents , reaction time , amount of catalyst and hydrogen peroxide , were investigated to obtain an optimal reaction conditions for phenol formation.
