摘　　要： 研究在不同时间、温度、液固比条件下苯乙烯对不溶性硫磺的萃取效率。在对普通硫磺溶解性研究实验中,相同温度下,苯乙烯对硫磺的溶解度大于甲苯和四氯乙烯。利用专业实验设计软件Design Expert安排实验,结果表明,在温度77℃、时间10min、液固比27时,提纯后的不溶性硫磺质量分数最大可达94.2%,萃取效率最大值91.1%,得到质量分数大于90%的高品位不溶性硫磺。 The effects of different factors such as time, temperature and solid-liquid ratio on the extraction of sulfur with styrene were investigated. It was found that the solubility sulfur in styrene is higher than those in toluene and tetrachloroethylene at the same temperature. The Design Expert software was used to arrange the experiment. The results showed that the value of insoluble sulfur extracted and the extraction ratio were up to 94.2% and 91.1%, respectively, at 77 ℃, extraction time 10 rain, and solid-liquid ratio of 27. Insoluble sulfurs of high quality were obtained under the above- mentioned conditions.
