摘要(Abstract)：

合成了以不同碳链长度的N-甲基咪唑[C6mim]+为阳离子,HSO4-、H2PO4-、CH3COO-为阴离子的一系列Brφnsted酸性离子液体,表征了其结构和酸性强度,以苯酚和甲醛合成双酚F的羟烷基化反应考察了它们的催化效果。在阳离子结构一定时,阴离子为HSO4-的离子液体酸性最强,催化效果最好;在阴离子结构一定时,随着阳离子中烷基链增加,酸性缓慢增加,但当烷基链中碳原子数为6时,催化效果最好。以[C6mim][HSO4]为酸催化剂,在反应时间60 min、酸/醛比1:1、原料酚醛比6:1、反应温度90℃的条件下双酚F的收率达到80.5%,选择性超过90%。该离子液体重复使用性好和腐蚀性低,有望成为一种极具发展潜力的双酚F合成催化剂。

关键词(KeyWords)： Brφnsted酸性离子液体;羟烷基化反应;催化合成;双酚F
