3.Production ọna:

① O ti gba nipasẹ iṣesi ti Dimethyl sulfate ati Sodium sulfide.Fi iyẹfun imi-ọjọ sinu ojutu iṣuu soda sulfide labẹ gbigbọn, gbe iwọn otutu soke si 80-90 ℃, fesi fun 1h, ki o dinku iwọn otutu ti Iwe-kemikali si iwọn 30 ℃;Dimethyl sulfate ti lọ silẹ sinu kettle ifaseyin, iṣesi naa tẹsiwaju fun 2h, ati lẹhinna distilled, duro fun fifin.Lẹhin ti o yapa ọti alkali egbin, ọja ti o pari ni a gba nipasẹ distillation.

② Dimethyl disulfide jẹ iṣelọpọ nipasẹ ọna Dimethyl sulfate ni ile-iṣẹ.

Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4

Fi iṣuu soda sulfide ti o lagbara ati omi sinu kettle ifaseyin, gbona wọn, ṣakoso iwọn otutu ni 50 ~ 60 ℃ lati tu iṣuu soda Chemicalbook sulfurized, lẹhinna fi imi-ọjọ equimolar sinu awọn ipele, jẹ ki o gbona fun 1h, tutu si 45 ℃, bẹrẹ sisọ Dimethyl sulfate, tọju iwọn otutu ifa laarin 40 ~ 45 ℃, jẹ ki o gbona fun 1h lẹhin fifi kun, ati lẹhinna yọ ọja Dimethyl disulfide kuro.Ni afikun, Dimethyl disulfide tun le ṣepọ nipasẹ ọna methyl mercaptan.

③ O jẹ iṣelọpọ nipasẹ iṣesi ti iṣuu magnẹsia iodomethyl ati Disulfur dichloride.O ti ṣẹda nipasẹ iṣesi ti iṣuu soda disulfide pẹlu iṣuu soda methylsulfate.Methyl Sodium thiosulfate ti pese sile nipa didaṣe Bromomethane pẹlu iṣuu soda thiosulfate, ati lẹhinna alapapo.
