Ethyl Thioglycolate (Ethyl Mercaptoacetate) (CAS: 623-51-8) yog siv los ua cov organic synthesis intermediate lossis tshuaj intermediate.Ethyl Thioglycolate yog reagent rau kev txiav txim siab ntawm hlau.Pharmaceutical intermediates rau synthesis ntawm cefmetazole.
Cov txiaj ntsig tau los ntawm esterification ntawm thioglycolic acid nrog ethanol nyob rau hauv muaj sulfuric acid.Thioglycolic acid, ethanol, thiab sulfuric acid tau rhaub hauv qab reflux rau 24 teev kom cais cov ester txheej, ntxuav plaub zaug nrog saturated brine, thiab tom qab ntawd qhuav dhau anhydrous sodium sulfate rau 24 teev.Cov khoom tau txais los ntawm fractional distillation ntawm atmospheric siab thiab sau cov 155-158 ℃ feem.
