1.Mankhwala katundu:
Kuwala chikasu mandala madzi.Pali fungo loipa.Sisungunuka m'madzi ndipo imatha kusakanikirana ndi ethanol, etha, ndi asidi acetic.
2.Cholinga:
Ntchito monga passivating wothandizila zosungunulira, catalysts, mankhwala intermediates, coking zoletsa, etc. Dimethyl disulfide amachitira ndi cresol kupanga 2-methyl-4-hydroxy anisulfide, ndiyeno condenses ndi O, O-dimethyl phosphoryl sulfide kolorayidi mu Chemical alkaline. sing'anga kupeza Fenthion.Ichi ndi mankhwala ophera tizilombo toyambitsa matenda a phosphorous omwe amagwira bwino ntchito komanso otsika kwambiri omwe amatha kuwononga mphutsi za mpunga, nyongolotsi za soya, ndi mphutsi za gadfly.Itha kugwiritsidwanso ntchito ngati mankhwala a Chowona Zanyama kuthetsa mphutsi za ng'ombe ndi nsabwe za khoma la ng'ombe.
3. Njira yopangira:
① Imapezedwa ndi zomwe Dimethyl sulfate ndi Sodium sulfide.Onjezani ufa wa sulfure mu njira ya Sodium sulfide poyambitsa, kwezani kutentha mpaka 80-90 ℃, tanini kwa 1h, ndikuchepetsa kutentha kwa Chemicalbook mpaka 30 ℃;Dimethyl sulphate imagwera mu ketulo yomwe imachitikira, zomwe zimapitirira kwa 2h, ndiyeno zimasungunuka, ndikuyimilira.Pambuyo kulekanitsa mowa wa alkali wotayidwa, chomalizidwacho chimapezedwa ndi distillation.
②Dimethyl disulfide imapangidwa ndi njira ya Dimethyl sulfate m'makampani.
Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
Ikani olimba Sodium sulfide ndi madzi mu ketulo anachita, kutentha iwo, kulamulira kutentha pa 50 ~ 60 ℃ kupasuka sulfure Chemicalbook sodium, ndiye kuwonjezera equimolar sulfure mu magulu, kusunga kutentha kwa 1h, kuziziritsa kwa 45 ℃, kuyamba. kuponya Dimethyl sulphate, kusunga kutentha anachita pakati pa 40 ~ 45 ℃, kusunga kutentha kwa 1h pambuyo kuwonjezera, ndiyeno nthunzi mankhwala Dimethyl disulfide.Kuphatikiza apo, Dimethyl disulfide imathanso kupangidwa ndi njira ya methyl mercaptan.
③Amapangidwa ndi zomwe iodomethyl magnesium ndi Disulfur dichloride.Amapangidwa ndi zochita za sodium disulfide ndi sodium methylsulfate.Methyl Sodium thiosulfate imakonzedwa pochita Bromomethane ndi Sodium thiosulfate, kenako kutentha.
4.Kusungirako ndi mawonekedwe amayendedwe:
Mpweya wabwino ndi kuyanika kwa kutentha kwa nyumba yosungiramo katundu;Sungani mosiyana ndi ma okosijeni ndi zidulo
5.Wozimitsa moto
ufa wouma, mchenga wowuma, mpweya woipa, thovu, 1211 wozimitsa
Pakadali pano, Jinan ZhongAn Industry Co., Ltd ikupereka DMDS kumisika yayikulu mosalekeza.Mu Seputembala chaka chino, Jinan ZhongAn Viwanda Co., Ltd adzakulitsa mzere wathu wopanga kuti akwaniritse zosowa za makasitomala ambiri.Timalandila ogula padziko lonse lapansi kuti atifunse.Kampani yathu yapezanso chiphaso cha ISO9001.Chonde khalani otsimikiza za mtundu wa malonda.
