Dimethyl disulfide: Cov khoom siv tshuaj lom neeg: lub teeb daj pob tshab kua. Muaj tus ntxhiab tsw. Insoluble hauv dej, miscible nrog ethanol, ether thiab acetic acid.
Siv: Siv los ua cov kuab tshuaj thiab tshuaj tua kab nruab nrab, roj thiab roj nplua nyeem ntxiv, coking inhibitors rau ethylene cracking furnaces thiab refining units, thiab lwm yam.
Siv los ua hnyav thiab tshuaj tua kab nruab nrab, thiab tseem yog cov khoom siv tseem ceeb ntawm methylsulfonyl chloride thiab methylsulfonic acid cov khoom.
GB 2760–1996 teev cov txuj lom zaub mov tso cai.
Dimethyl disulfide, tseem hu ua dimethyl disulfide, yog siv nyob rau hauv lub synthesis ntawm organophosphorus tshuaj tua kab fenthion thiab fenthionate li intermediates p-methylthio-m-cresol thiab thiopropyl raws li ib tug intermediate p-methylthio Phenol kuj siv raws li ib tug purifying tus neeg sawv cev rau cov kuab tshuaj thiab catalyst.
Siv raws li cov kuab tshuaj, catalyst passivants, tshuaj tua kab intermediates, coking inhibitors, thiab lwm yam Dimethyldisulfide reacts nrog cresol los ua 2-methyl-4-hydroxyanisole sulfide, uas yog ces condensed nrog O, O-dimethylphosphorus sulfide chloride nyob rau hauv ib tug alkaline Chemicalbook nruab nrab kom tau txais f . Qhov no yog cov tshuaj tua kab mob organophosphorus uas muaj txiaj ntsig zoo thiab tsis tshua muaj tshuaj lom nrog kev tswj xyuas zoo ntawm cov nplej borers, soybean borers thiab gadfly larvae. Nws kuj tseem siv tau los ua cov tshuaj kho tsiaj kom tshem tawm cov nyuj ya maggots thiab nyuj zuam.

Txoj kev tsim khoom: Ua los ntawm cov tshuaj tiv thaiv ntawm methylmagnesium iodide thiab disulfide dichloride. Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm disodium disulfide thiab sodium methyl sulfate. Nws yog tsim los ntawm reacting methyl bromide thiab sodium thiosulfate kom tau sodium methyl thiosulfate, uas yog ces rhuab.
