石油化工 1994年第4期23卷 252-258页

作者：朱中南陆仁杰乐慧慧张浩戴干策华东理工大学联合化学反应工程研究所

从工程观点阐述由光气和双酚Ａ经界面缩聚制聚碳酸酯的反应过程。整个缩聚过程可以分成两个阶段。在第一阶段，为了达到后续反应所需的合适摩尔配比，光气的水解副反应必须小心地控制；在第二阶段，为了确保得到高分子量聚合物，需要足... 详细信息

从工程观点阐述由光气和双酚Ａ经界面缩聚制聚碳酸酯的反应过程。整个缩聚过程可以分成两个阶段。在第一阶段，为了达到后续反应所需的合适摩尔配比，光气的水解副反应必须小心地控制；在第二阶段，为了确保得到高分子量聚合物，需要足够的反应时间。与此相对应，在第一阶段，建议使用带有静态混合器的管式反应器，而在第二阶段，采用多级釜式搅拌反应器是有利的。
