摘要
Ionic liquids have been used as catalysts for Blanc reaction of toluene. The effects of reaction temperature, reaction time and dosage of the ionic liquid catalyst have been investigated, and the catalytic performance of different ionic liquid catalysts for toluene chloromethylation was also studied. The reaction was found to proceed under mild conditions with excellent conversion （up to 90%） in the absence of Lewis acids. The ionic liquids could be recycled and reused without loss of their catalytic activities.
爱奥尼亚的液体为甲苯的 Blanc 反应被用作催化剂。离子的液体催化剂的反应温度，反应周期和剂量的效果被调查了，并且为甲苯 chloromethylation 的不同离子的液体催化剂的催化表演也被学习。反应被发现当路易斯酸不在时在温和条件下面继续优秀变换(多达 90%) 。没有他们的催化活的损失，离子的液体能被再循环并且再使用。
