| 摘 要： | 合成了苯乙烯型强碱阴离子交换树脂,将其用于环氧乙烷催化水合制乙二醇反应中,研究了温度、浓度、空速对树脂催化性能的影响,探讨了树脂的不可逆膨胀及失活原因.结果表明,在393K树脂发生降解,降解物与环氧乙烷反应生成聚乙二醇胺,导致树脂膨胀破裂;在温度353K,压力1.5MPa,液时空速0.2h-1下,环氧乙烷转化率100%,乙二醇的选择性96.3%,使用1600h后,催化剂的膨胀率6%,强碱容量损失率7.5%.

| Abstract: | A strongly basic anion exchange resin was prepared in this paper,then it was converted to bicarbonate type to catalyze EO hydration. The influences of temperature,concentration and space velocity on catalytic activity have been investigated. The mechanism of swelling and deactivation of the resin catalyst have been studied. The results show that degradation takes place in the resin at 393K,and then the decomposition product reacted with EO to form polyethyleneglycolamine. EO conversion rate and EG selectivi... |
