汞硝矾法制氧化汞的模拟实验研究

AN INVESTIGATION OF THE SIMULATED EXPERIMENTS ON REFINNING MERCURY OXIDE WITH ALUM-SALTPETRE-MERCURY

中国制氧化汞的历史悠久。从明代开始形成了用升炼明矾—硝石—水银混合物的办法制纯氧化汞——“红升丹”的独创路线。本文通过模拟实验的方法验证了这一古法制高纯度氧化汞的可行性;提出了这一方法的化学反应原理.该模拟实验的操作法和配方可供现代制备中药“红升丹”参考.

The history of preparing red mercury oxide (HgO) in our country is very long. Since the Ming Dynasty, the unique way to refine the high-quality mercury oxide called 'hong sheng-dan' by heating the mixture of alum-saltpetre-mercury has been gradually formed. Through many simulated expri-ments, this article proves the practicability of this method and it also points out the mechanism of its chemical reaction. The operative skills of the simulated experiment and the composition can be kept for the reference for refinning the 'Hong Sheng-dan' at the present day.
