【摘要】 固体超强酸ＺｒＯ２／ＳＯ４＝和Ｆｅ２Ｏ３／ＳＯ４＝在室温下即可高活性地催化苯乙烯烷基化甲苯的反应。于２０分钟时苯乙烯转化率可达４０％～５０％。在连续使用三次时，催化剂活性未见下降更多还原

【Abstract】 Solid superacids ZrO 2/SO 4 =and Fe 2O 3/SO 4 =can catalyze the alkylation reaction of toluene by styrene with high activities at room temperature. About 40～50% conversion of styrene was reached at 20 minutes. The activities of catalysts were not changed in continuously using for three times.更多还原
