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

1.Lintho tsa lik'hemik'hale:

Mokelikeli o mosehla o bonaletsang.Ho na le monko o litšila.Ha e qhibilihe ka metsing 'me e ka tsoakoa le ethanol, ether le acetic acid.

2.Morero:

Dimethyl disulfide e sebetsana le cresol ho hlahisa 2-methyl-4-hydroxy anisulfide, ebe e kopana le O, O-dimethyl phosphoryl sulfide chloride ka har'a Chemical alkaline. mahareng ho fumana Fenthion.Sena ke sebolaea-likokoanyana sa phosphorus se sebetsang hantle le se nang le chefo e tlase se nang le litlamorao tse ntle tsa taolo holim'a libora tsa raese, soybean heartworms, le libokoana tsa libolu.E ka boela ea sebelisoa e le moriana oa bongaka oa liphoofolo ho felisa likokoanyana tsa cowfly le linta tsa lebota la khomo.

3.Mokhoa oa tlhahiso:

① E fumanoa ka karabelo ea Dimethyl sulfate le Sodium sulfide.Kenya phofo ea sebabole ka har'a tharollo ea sodium sulfide tlas'a ho hlohlelletsa, phahamisa mocheso ho 80-90 ℃, itšoara bakeng sa 1h, 'me u theole mocheso oa Chemicalbook ho hoo e ka bang 30 ℃;Dimethyl sulfate e oela ka har'a kettle ea karabelo, karabelo e tsoela pele bakeng sa 2h, ebe e silafatsoa, ​​e emetse ho beha.Kamora ho arola joala bo litšila ba alkali, sehlahisoa se feliloeng se fumanoa ka distillation.

②Dimethyl disulfide e entsoe ka mokhoa oa Dimethyl sulfate indastering.

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

Kenya sulfide e tiileng ea sodium le metsi ka har'a kettle ea karabelo, li futhumale, laola mocheso ho 50 ~ 60 ℃ ho qhaqha sodium e entsoeng ka sulfurized Chemicalbook, ebe u eketsa sebabole se lekanang ka lihlopha, se futhumetse bakeng sa 1h, se pholise ho 45 ℃, qala. ho theola Dimethyl sulfate, boloka mocheso oa karabelo pakeng tsa 40 ~ 45 ℃, e boloke e futhumetse bakeng sa 1h ka mor'a ho eketsa, ebe o mouoane sehlahisoa Dimethyl disulfide.Ho feta moo, Dimethyl disulfide e ka boela ea etsoa ka mokhoa oa methyl mercaptan.

③ E hlahisoa ke karabelo ea iodomethyl magnesium le Disulfur dichloride.E thehoa ke karabelo ea sodium disulfide ka sodium methylsulfate.Methyl Sodium thiosulfate e lokisoa ka ho arabela Bromomethane ka Sodium thiosulfate, ebe e futhumatsa.

4. Litšobotsi tsa polokelo le lipalangoang:

Ho kenya moea le ho omisa ka mocheso o tlase oa ntlo ea polokelo;Boloka ka thoko ho li-oxidants le acid

5.Setima-mollo

Phofo e omileng, lehlabathe le omeletseng, carbon dioxide, foam, sesebelisoa sa ho tima 1211

Hajoale, Jinan ZhongAn Industry Co., Ltd e ntse e tsoela pele ho fana ka DMDS limmarakeng tse kholo.Ka Loetse selemong sena, Jinan ZhongAn Industry Co., Ltd e tla holisa mohala oa rona oa tlhahiso ho fihlela litlhoko tsa bareki ba bangata.Re amohela bareki ho tsoa lefats'eng lohle ho tla buisana le rona.Khamphani ea rona e boetse e fumane setifikeiti sa ISO9001.Ka kopo, kholiseha ka boleng ba sehlahisoa.
