摘要
本文从节约药品用量、减少环境污染和方便学生操作等方面设计了去离子水、四氯化锡、六氯合铅酸锭的微型制备和乙酸乙酯的微型合成方法,并与常规实验进行了对比研究。
This paper has designed microscale experiment for the preparation of distilled deionized wa-ter, SnCl4, (NH4)2 [PbCl]6 and synthesis of CH3COOC2H5, considering the amount of materials, the problem of pollution, and to agree with the operation of the students. After that the author had also studied the defferents between microscale laboratory and the common experiment.
