转化法制备硝酸钾微型实验的探究

Exploration of the improvement on potassium nitrate preparation with conversion method

该文介绍了一种在常规实验的基础上，把转化法制备硝酸钾实验设计为微型实验，可省去甘油浴，并对其中的热过滤部分进行改进，大大缩短了实验时间，操作简单、产率高、实验效果显著。

It is reported that the experiment is designed microscale experiment on the basis of normal experiment which is the potassium nitrate preparation with conversion method. It can dispense with glycerine bath, and improve the operation of heat filtration. It also can reduce much time of carrying on experiment. The method is fairly good with simplicity, high productivity and the conspicuous effect.
