摘　　要：介绍了有机硫极压剂的发展动向，探讨了连续化生产极压剂硫化异丁烯中间体硫氯化异丁烯的生产工艺及实验结果。当前生产中所产生的方法均为间歇法，即将氯化硫加入反应釜中，通入异丁烯，控制反应温度，通常需要28～32h／釜。限制了产量的提高。提高产量就要增加设备，占地面积大，限制了脱氯工序的生产。连续化生产硫氯化异丁烯，很好解决了反应热的移出，避免了反应过程中局部过热，导致色泽过深。使反应速度加快1倍以上，产品色泽明显降低。投资少，占地面积小，改善了生产环境，用它作为原料经脱氯处理后，所得到的硫化异丁烯，色泽浅，其它各项指标均附和标准。具有很大的经济意义。This paper introduces the trend of organic sulphur extreme pressure.It discusses production technology and experiment result of sulfochlorcide isobtenyl which is midst of continuous production extreme pressure sulphide isobutyi. current production ways. are interruption wais that is putling sulfur chloride in the reaction container through isobutene controling reoction temperature,it usually takes 28-32hours per container It restricts raising of production. raising production needs adding equipment. increasing areas and resticting production of getling off chlorine.continuous production sulfochlorcide isobtenyl solves the emigrant of heat of reaction, advoids partial heat during the caurse of reaclion, causes deep colur. reaction speed is as more than two times as old reaction speed. production colour drops obviously.investment and areas are small.it improves production enviroment.take isobutene as raw material through getting off chlorine, attaining sulfochlorcide isobotenyl. its colour is light colour. other all kinds of guideline follow level. It has very large economy meaning.
