Prepare sodium polysulfide with coking black sulfur
Sodium polysulfide was prepared by black sulfur as the raw materials. The affect of ratio of reac-tants, temperature and time on the yield were studied in this paper. The results indicate, Sodium sulfide and black sulfur molar ratio of 1:1,2; reaction temperature 80-85℃; under the conditions of the reaction of 2 hours, the reac-tion yield was up to 93,5%.
