摘要
从理论和实验两个方面对由盐酸和二氧化锰制取氯气的反应条件进行了研究，得到了实验室制备氯气所需的适宜的盐酸浓度为７～９ｍｏｌ·ｄｍ－３，反应温度为３３３～３５３Ｋ．
The preparation of chlorine by the reaction of hydrochloric acid against manganese dioxide in laboratory has been theoretically and experimentally researched. The appropriate reaction temperature 333～353K and the concentration 7～9 mol. din-3 of the hydrochloric acid have been found for preparing it.
