氯化钠在有机化学实验中使用目的探究

The Intended Use of Sodium Chloride in Organic Chemistry Experiment

在有机化学实验中经常使用氯化钠固体或饱和氯化钠溶液,它在不同的实验中有不同的作用。本文主要对氯化钠在环己烯的制备、乙酸乙酯的制备及在羧酸及硫酸钠盐型有机试剂纯制中的应用等有机化学实验中的使用进行探究。通过苯胺的制备实验中加入氯化钠与未加氯化钠所制得苯胺的产量与苯胺析出时间进行对比,得出加入氯化钠能提高产量,缩短苯胺析出的时间。

Solid sodium chloride or saturated solution of sodium chloride was used frequently in Organic Chemistry Experiment, with the different functions depending on experiments. The research on the application of sodium chloride in preparation of cyclohexene, ethyl acetate and purification of organic reagents like the type of carboxylic acid or salt of sodium sulfate was carried out. Through the comparison of the yield and release time of phenylamine in preparation of phenylamine with sodium chloride or without sodium chloride, it showed that the yield can be improved and cut the release time of phenylamine shortened.
