Dimethyl Disulfide (DMDS) CAS 624-92-0 Purity > 99.5% (GC) Hoobkas

Dimethyl Disulfide (DMDS) (CAS: 624-92-0) yog ib qho organic disulfide uas yog methane nyob rau hauv uas ib qho ntawm cov hydrogens tau hloov los ntawm ib pawg methyldisulfanyl, nws muaj diffuse khaus dos tsw.Txawm hais tias muaj coob tus pom nws cov ntxhiab tsw tsis txaus ntseeg ntawm qhov siab siab, thaum diluted, nws cov aroma kuj tau piav qhia tias qab ntxiag.Dimethyl Disulfide feem ntau yog siv ua ke nrog lwm cov tshuaj tsw qab hauv cov khoom noj, nrog rau cov khoom ci, cheese, cov khoom noj khov khov, cov khoom noj nqaij, kua zaub, savory flavour, txiv hmab txiv ntoo flavors, mos khoom qab zib, gelatin, puddings, thiab ob qho tib si cawv thiab tsis muaj cawv.Nws pom daim ntawv thov nyob rau hauv tus neeg sawv cev flavoring thiab ib tug corrosion inhibitor.Sulfur Compounds.Flavour thiab Fragrance Chemical Compounds.Kev lag luam, Dimethyl Disulfide kuj tseem siv los ua tus neeg sawv cev sulfiding rau catalyze cov tshuaj tiv thaiv hauv cov roj refineries thiab lwm yam lag luam.Dimethyl Disulfide yog dav siv nyob rau hauv cov organic synthesis thiab tshuaj tua kab intermediates.Siv los ua cov kuab tshuaj, passivator rau catalyst.Siv los ua roj thiab lubricant additive.Nws tseem yog cov khoom siv tseem ceeb rau cov khoom methanesulfonyl chloride thiab methanesulfonic acid cov khoom, nrog rau catalyst vulcanization thiab passivating tus neeg sawv cev.Kev npaj Dimethyl Disulfide tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm imethyl sulfate thiab sodium sulfide.Nyob rau hauv stirring, sulfur hmoov tau ntxiv rau hauv sodium sulfide tov.Cov tshuaj tiv thaiv saum toj no tau ua kom sov txog 80-90 ℃, tom qab cov tshuaj tiv thaiv rau 1 h, txias txog li 30 ℃.Dimethyl Sulfate tau poob rau hauv cov tshuaj tiv thaiv kab mob thiab cov tshuaj tiv thaiv txuas ntxiv rau 2h.Tom qab ntawd, distillation, stratification, cais cov khib nyiab alkali cawv, tom qab ntawd los ntawm distillation thiab cov khoom kawg yog npaj.Hauv kev lag luam, Dimethyl sulfate txoj kev yog saws los ua ke dimethyl disulfide.
