摘　　要：以HY沸石为催化剂,在固定床反应器中,进行间甲酚与叔丁醇的烷基化反应合成2-叔丁基-5-甲基苯酚的实验。考察了反应温度、液态空速、间甲酚与叔丁醇投料摩尔比对HY沸石催化性能的影响,并考察了催化剂的稳定性。实验结果表明,HY沸石在相对低的反应温度下表现出高活性、高选择性及稳定性,有潜在的应用价值。Zeolite HY was used as catalyst for alkylation of m - cresol with tert -butyl alcohol. Reaction conditions such as temperature, liquid space velocity and tert - butyl alcohol/m - cresol mole ratio significantly influenced distribution of products. Zeolite HY exhibited high activity, selectivity and stability and therefore has potential application for producing 2 - tert -butyl-5-methyl phenol in a flow system at a relatively low reaction temperature of 383 K.
