I-Dimethyl Disulfide (CAS: 624-92-0) Ulwazi (CAS: 624-92-0)

1.Iimpawu zeMichiza:

Ulwelo olukhanyayo olutyheli olucacileyo.Kukho ivumba elibi.Ayinyibiliki emanzini kwaye inokuxutywa ne-ethanol, i-ether, kunye ne-acetic acid.

2. Injongo:

Isetyenziswe njenge-agent edlulayo kwi-solvents, i-catalysts, i-pesticide intermediates, i-coking inhibitors, njl njl. medium ukufumana Fenthion.Esi sisitshabalalisi se-phosphorus esisebenzayo nesinetyhefu esezantsi eneziphumo ezigqwesileyo zolawulo kwiibhontshisi zesoya, kunye nemibungu yeempukane.Isenokusetyenziswa njengeyeza lezilwanyana ukuphelisa iimpethu zenkomo kunye neentwala zodonga lwenkomo.

3.Indlela yokuvelisa:

①Ifumaneka ngokusabela kweDimethyl sulfate kunye neSodium sulfide.Yongeza umgubo wesulfure kwisisombululo seSodium sulfide phantsi kokuvuselela, phakamisa ubushushu ukuya kwi-80-90 ℃, uphendule i-1h, kwaye wehlise ubushushu be-Chemicalbook malunga ne-30 ℃;I-Dimethyl sulfate iphonswa kwi-kettle yokusabela, impendulo iyaqhubeka i-2h, kwaye i-distilled, imele i-layer.Emva kokwahlula inkunkuma ye-alkali yotywala, imveliso egqityiweyo ifunyenwe nge-distillation.

②I-Dimethyl disulfide idityaniswe yindlela ye-Dimethyl sulfate kwishishini.

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

Beka i-Sodium sulfide eqinileyo kunye namanzi kwi-kettle yokusabela, zifudumeze, zilawule ubushushu kwi-50 ~ 60 ℃ ukunyibilikisa i-sodium ye-Chemicalbook enesulfurized, emva koko wongeze i-sulfure elinganayo kwiibhetshi, yigcine ishushu i-1h, ipholise ukuya kuma-45 ℃, qalisa. Ukulahla i-Dimethyl sulfate, gcina ubushushu be-reaction phakathi kwe-40 ~ 45 ℃, yigcine ishushu i-1h emva kokudibanisa, kwaye ikhuphe imveliso ye-Dimethyl disulfide.Ukongeza, i-Dimethyl disulfide inokuphinda yenziwe ngendlela ye-methyl mercaptan.

③Iveliswa ngokusabela kwe-iodomethyl magnesium kunye neDisulfur dichloride.Yenziwa ngokusabela kwe-sodium disulfide kunye ne-sodium methylsulfate.I-Methyl Sodium thiosulfate ilungiswa ngokuphendula i-Bromomethane kunye ne-Sodium thiosulfate, kwaye emva koko iyafudumeza.

4.Ugcino kunye neempawu zokuhamba:

Ukungena komoya kunye nokomisa ubushushu obuphantsi kwendawo yokugcina impahla;Gcina ngokwahlukileyo kwii-oxidants kunye neeasidi

5.I-arhente yokucima umlilo

I-powder eyomileyo, isanti eyomileyo, i-carbon dioxide, i-foam, i-arhente yokucima i-1211
