Etherification of Isoamylenes with Methanol in Reactive Distillation Collumn

研究异戊烯和甲醇在反应蒸馏柱中以苯磺酸阳离子交换树脂为催化剂 ,在 40～ 80℃醚化的转化率随反应条件的变化。结果表明 ,在 6 9℃、n(异戊烯 ) /n(甲醇 ) =1/1.2时 ,异戊烯醚化反应的转化率最高 ;反应压力对异戊烯醚化反应的转化率影响不大The change of etherification conversions against reaction conditions has been studied in reactive distillation columns at temperatures of 40～80 ℃.A benzene sulfonate cationexchange resin was used as catalyst.Results show that the conversion is the highest at a temperature of 69 ℃ and a molar ratio of methanol to isoamylenes of 1.2. The etherification conversion of isoamylenes is less dependent on the reaction pressure.These results are of significant importance in the comprehensive utilization of isoamylenes in FCC factory
