1.Izakhiwo zamakhemikhali:
Uketshezi olukhanyayo oluphuzi olukhanyayo.Kukhona iphunga elibi.Ayincibiliki emanzini futhi ingaxutshwa ne-ethanol, i-ether, ne-acetic acid.
2.Inhloso:
Isetshenziswa njenge-passivating agent yezinyibilikisi, ama-catalysts, in pesticide intermediates, coking inhibitors, njll. I-Dimethyl disulfide isabela ne-cresol ukuze ikhiqize i-2-methyl-4-hydroxy anisulfide, bese ihlangana ne-O, O-dimethyl phosphoryl sulfide chloride ku-Chemicalbook alkaline. medium ukuthola Fenthion.Lesi isibulala-zinambuzane se-organic phosphorus esisebenzayo nesinobuthi obuphansi esinemiphumela emihle kakhulu yokulawula eziphuzweni zerayisi, izikelemu zenhliziyo zikabhontshisi wesoya, nezibungu ze-gadfly.Ingasetshenziswa futhi njengomuthi wezilwane ukuqeda izimpethu ze-cowfly kanye nezintwala zodonga lwezinkomo.
3.Indlela yokukhiqiza:
①Itholakala ngokusabela kwe-Dimethyl sulfate ne-Sodium sulfide.Faka impushana yesibabule esixazululweni se-Sodium sulfide ngaphansi kokunyakaziswa, phakamisa izinga lokushisa libe ku-80-90 ℃, usabele ihora elingu-1, bese wehlisa izinga lokushisa le-Chemicalbook libe ngu-30 ℃;I-Dimethyl sulfate iphonswa eketelani lokusabela, ukusabela kuyaqhubeka i-2h, bese i-distilled, imele ukubeka.Ngemva kokuhlukanisa udoti we-alkali yotshwala, umkhiqizo oqediwe utholakala nge-distillation.
②I-Dimethyl disulfide ihlanganiswa ngendlela ye-Dimethyl sulfate embonini.
I-Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
Faka i-Sodium sulfide eqinile namanzi kugedlela lokusabela, uwashise, lawula izinga lokushisa ku-50 ~ 60 ℃ ukuze uncibilikise i-sodium ye-Chemicalbook esulfure, bese wengeza isulfure elinganayo ngamaqoqo, uyigcine ifudumele ihora elingu-1, uyipholise ibe ngu-45 ℃, qala. yehlisa i-Dimethyl sulfate, gcina izinga lokushisa lokusabela liphakathi kuka-40 ~ 45 ℃, ligcine lifudumele ihora elingu-1 ngemva kokungeza, bese uhwamulisa umkhiqizo we-Dimethyl disulfide.Ngaphezu kwalokho, i-Dimethyl disulfide ingabuye ihlanganiswe ngendlela ye-methyl mercaptan.
③Ikhiqizwa ukusabela kwe-iodomethyl magnesium ne-Disulfur dichloride.Yakhiwa ukusabela kwe-sodium disulfide nge-sodium methylsulfate.I-Methyl Sodium thiosulfate ilungiswa ngokuphendula i-Bromomethane nge-Sodium thiosulfate, bese iyafudumeza.
4.Isitoreji nezici zokuthutha:
Ukungena komoya kanye nokomisa izinga lokushisa eliphansi kwendawo yokugcina impahla;Gcina ngokwehlukana nama-oxidants nama-asidi
5.I-ejenti yokucima umlilo
Impushana eyomile, isihlabathi esomile, i-carbon dioxide, igwebu, i-ejenti yokucisha 1211
Njengamanje, iJinan ZhongAn Industry Co., Ltd iqhubeka nokuhlinzeka nge-DMDS ezimakethe ezinkulu.NgoSepthemba walo nyaka, iJinan ZhongAn Industry Co., Ltd izonweba umugqa wethu wokukhiqiza ukuze uhlangabezane nezidingo zamakhasimende amaningi.Samukela abathengi abavela emhlabeni wonke ukuthi baxhumane nathi.Inkampani yethu iphinde yathola isitifiketi se-ISO9001.Sicela uqiniseke ngekhwalithi yomkhiqizo.
