Kugwiritsa ntchito
Dimethyl Disulfide (DMDS) ndi mankhwala ophatikizira a C2H6s2. Ndi fungo lopanda utoto ndi fungo lamphamvu, losasangalatsa. Nazi zina mwazomwe zimagwiritsidwa ntchito:
1. M'makampani a petroleum: DMDS amagwiritsidwa ntchito kwambiri ngati sulufule - yokhala ndi zowonjezera mu petroleum kuyeretsa. Zimathandizira kukonza mwaluso njira za njira zopangira mapulogalamu pochita ngati gwero la sulufule. Itha kuchitira ndi ma oxis oxis pamwamba pa canlfurization canlfurization canlfirization, kulimbikitsa ntchito zawo, ndikuwongolera mu kuchotsera kwa sulfure - wokhala ndi mankhwala ku mankhwala a mafuta a petroleum.
2. Mu makampani opanga mankhwala: Ndi chinthu chofunikira chopangira kaphatikizidwe ka sulfure osiyanasiyana organic - okhala ndi mankhwala. Mwachitsanzo, itha kugwiritsidwa ntchito kukonzekera methanethithiol, yomwe imagwiritsidwa ntchito popanga mankhwala ophera tizilombo, mankhwala osokoneza bongo, ndi mankhwala ena abwino. DMDS imatha kugwiritsidwanso ntchito pophatikizika kwa sulfure wina - wokhala ndi heterocyccyclic mankhwala, omwe ali ndi mapulogalamu ofunikira m'munda wa synthec synthesi.
3. Monga fumigant: chifukwa cha kuwopsa kwake kwa tizilombo ndi tizilombo tating'onoting'ono, ma DMDS itha kugwiritsidwa ntchito ngati fimagant yoletsa tizirombo ndi bowa mumitengo yosungidwa, malo osungirako nyumba zakale. Imatha kupha tizirombo ndi bowa, kuthandiza kuteteza zinthu zosungidwa ndikupewa kufalikira kwa matenda.
4. Pamunda wamagetsi: DMDS imagwiritsidwa ntchito m'makampani a semiconducy pa njira zina monga mankhwala opaka mankhwala (CVD). Itha kugwiritsidwa ntchito kuyika sulfure - yokhala ndi mafilimu oonda, omwe ali ndi ntchito zomwe zili ndi zida zamagetsi monga omasulira ndi masensa.
5. M'macheri a Chemistry: DMDS itha kugwiritsidwa ntchito ngati choponderezedwa mu chemistry. Zitha kuchitirana magulu ena ogwirira ntchito omwe amapanga zotumphukira ndi chromatographraphic kapena katundu wowoneka bwino, kuwongolera kupatukana ndi kudziwika ndi zinthu izi. Mwachitsanzo, itha kugwiritsidwa ntchito powunikira acids acid ndi zina zopangidwa ndi mafuta a chromatography - misa sportrometry (GC - MS).
Pitilizani ndikusunga
Moyo wa alumali: Mwezi 24 kuyambira tsiku lopanga mu phukusi lokhazikika losagwirizana ndi dzuwa louma, madzi.
Chosokoneza chosungira, kuyanika kwa kutentha kochepa, kupatulidwa ndi oxidants, ma acid.
