1　引　　言传统分子筛柱的制备以静态涂敷或以水、甲醇为悬浮液的动态涂敷为主 ,两种方法耗时耗力、成功率低、重复性均匀度差。与此相比 ,本文发展的以一缩二乙二醇为悬浮剂的改进涂敷法简便易行、重复性好、柱效高 ,极大地拓展了分子筛柱的应用范围。利用该涂敷法 ,本文制备 1 Introduction The preparation of traditional molecular sieve column with static coating or water, methanol suspension as the main dynamic coating, the two methods time-consuming, low success rate, poor repeatability. Compared with this, the improved coating method with diethylene glycol as suspending agent developed in this paper is simple and easy to operate with good repeatability and high column efficiency, greatly expanding the application range of molecular sieve columns. With this coating method, it is prepared herein
