Study on Whole Process Flow of Extracting Purification in Synthesis Course of Vulcanizing Promoter M— The Section of Extracting Purification

FAN Wen ge(Department of Chemistry,Northwest Minorit University,Lanzhou 730030 China)  
The sodium salt of crude M(2 Mercaptobenzothiazole) is purified,while using CS 2 as an extracting agent.Some factors that influence the process(including extracting times,amount of extracting agent,concentration and pH of M Na salt,etc.) were studied at normal temperature and pressure.The results demonstrated that the product quality of vulcanizing promoter M which is purified through the process fits in with national standard.Compared with popular process,the product yield is raised ,energy consumption and raw material consumption is reduced.
