硫磺还原法制取氢溴酸的研究

采用硫磺还原法制取氢溴酸，实验考察了原料配比、溴滴加速率、反应时间、反应温度等因素对反应的影响，还考察了硫循环使用情况．在实验条件下，所得的氢溴酸浓度达到50％以上，氢溴酸的平均收率高达75％以上．

Study on Production of Bromohydric Acid by Reduction of Sulfur

Bromohydricy acid was produced by the reduction of sulfur. The test investigated such factors to the reaction as the ratio of raw material, the velocity of dropwise adding bromine , the reaction time and the reaction temperature,and also investigated the use of circulatory sulfur. Under the experimental conditions the concentration of bromohydric acid was above 50%,and the mean yield of bromohydric acid was more than 75%.
