Dimethyl Disulfide (CAS: 624-92-0) Ọmụma (CAS: 624-92-0)

1.Njirimara kemịkalụ:

Mmiri mmiri na-egbuke egbuke edo edo.Enwere isi ísì ọjọọ.Ọ naghị agbaze na mmiri, a pụkwara ịgwakọta ya na ethanol, ether, na acetic acid.

2. Nzube:

A na-eji ya dị ka onye na-agafe agafe maka ihe mgbaze, ndị na-emepụta ihe, ndị na-emepụta pesticide intermediates, coking inhibitors, wdg. Dimethyl disulfide na-emeghachi omume na cresol iji mepụta 2-methyl-4-hydroxy anisulfide, wee condenses na O, O-dimethyl phosphoryl sulfide chloride na Chemicalbook alkaline. ọkara iji nweta Fenthion.Nke a bụ ihe na-arụ ọrụ nke ọma na obere nsí organic phosphorus ụmụ ahụhụ nwere mmetụta nchịkwa dị mma na nsị osikapa, soybean heartworms, na larvae gadfly.Enwere ike iji ya dị ka ọgwụ ọgwụgwọ ọrịa anụmanụ iji kpochapụ ikpuru ehi na ikpuru mgbidi ehi.

3.Production usoro:

① A na-enweta ya site na mmeghachi omume nke Dimethyl sulfate na sodium sulfide.Tinye sọlfọ ntụ ntụ n'ime ngwọta sodium sulfide n'okpuru mkpali, bulie okpomọkụ ruo 80-90 ℃, meghachi omume maka 1h, ma belata okpomọkụ nke akwụkwọ Chemical ruo ihe dịka 30 ℃;A na-atụba Dimethyl sulfate n'ime kettle mmeghachi omume, mmeghachi omume na-aga n'ihu maka 2h, wee distilled, guzo maka ịkwa akwa.Mgbe ekewapụ ihe ọṅụṅụ alkali n'efu, a na-enweta ngwaahịa a rụchara site na distillation.

② A na-emepụta Dimethyl disulfide site na usoro Dimethyl sulfate na ụlọ ọrụ.

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

Tinye Sodium sulfide siri ike na mmiri n'ime kettle mmeghachi omume, kpoo ha, jikwaa okpomọkụ na 50 ~ 60 ℃ iji gbazee sulfurized Chemicalbook sodium, wee tinye sọlfọ equimolar na batches, mee ka ọ dị ọkụ maka 1h, mee ka ọ dị jụụ ruo 45 ℃, malite. idobe Dimethyl sulfate, debe mmeghachi omume mmeghachi omume n'etiti 40 ~ 45 ℃, na-ekpo ọkụ maka 1h mgbe agbakwunyere, wee kpochapu ngwaahịa Dimethyl disulfide.Na mgbakwunye, Dimethyl disulfide nwekwara ike iji usoro methyl mercaptan mepụta ya.

③ A na-emepụta ya site na mmeghachi omume nke iodomethyl magnesium na Disulfur dichloride.Emebere ya site na mmeghachi omume nke sodium disulfide na sodium methylsulfate.A na-akwado Methyl Sodium thiosulfate site na imeghachi omume Bromomethane na Sodium thiosulfate, wee kpoo ọkụ.
