【摘要】 考察了不溶性硫磺制备过程中在聚合、淬冷、萃取、充油工序加入稳定剂对产物中不溶性硫磺含量及稳定性的影响。结果表明,每种工序中添加的稳定剂均能提高产物中不溶性硫含量及其稳定性,其中聚合反应中加入醇类稳定剂D、淬冷中加入水溶性有机稳定剂A、萃取中加入液态酯类稳定剂X、充油中加入酯类稳定剂X效果最好。另外,在单剂评选的基础上,进行了两剂组合优化方案试验,两剂组合对不溶性硫磺含量及其稳定性无复合叠加作用。更多还原

【Abstract】 The effects of adding various stabilizers in the production steps,such as polymerization, quenching,extraction and oil treatment,on the insoluble sulfur(IS)content and stability of product were studied.Test results showed that the IS content and the stability of product could be improved by adding stabilizers in each step;the optimum selections were adding alcoholic stabilizer D in polymerization,water soluble organic stabilizer A in quenching and ester type liquid stabilizer X in extraction and oil treatment. Besides,based on the single stabilizer test results,optimization tests of two-stabilizer combination were carried out,yet no positive synergetic effect was observed.更多还原
