  在不使用脱水剂的情况下，由常压二氧化碳和二醇直接合成聚碳酸酯二醇

  摘要：

  从绿色化学的角度来看，以 CO 2作为 C1 化学品的聚合物合成已引起广泛关注。CO 2和二醇直接转化为聚碳酸酯二醇有望作为危险的光气工艺的替代方法，但是，由于 CO 2的惰性特性和热力学限制，具有挑战性。在此，我们介绍了使用非均相 CeO 2催化剂和 CO 2流半间歇反应器从常压 CO 2和 α,ω-二醇直接合成聚碳酸酯二醇。来自 CO 2的目标交替聚碳酸酯二醇并且在不使用任何脱水剂的情况下以高产率（92%）和选择性（97%）获得了1,6-己二醇。通过CeO 2催化剂活化大气压CO 2以及通过去除联产水（气提）使平衡向产物移动是高产率的原因。带有CeO 2催化剂的流动反应体系适用于CO 2与伯一元醇或1,2-二醇的反应，以高选择性(>99%)得到目标有机碳酸酯。
