摘要 本文叙述一种用悬浮分散——热固化方法制备球形再生纤维素小球(白球)、并用白球/环氧氯丙烷/有机胺/乙醇体系一步法制备球形纤维素阴离子交换剂的新方法。对交换剂性能进行了测试。 This Paper describes a new method for the preparation of an anionexchange regenerated cellulose microball. The process consists of two steps. First is the preparation of regenerated cellulose microball (white ball) by suspension-thermol solidification of sodium salt of cellulose xanthate. Secondly, the resulted white ball is etherified with epichlorohydrin and ethanol and then aminated with amine in the same reactor. The properties of resulted anion exchange cellulose microball were studied.
