Mawu Oyamba
Dimethyl disulfide (DMDS) ndi organic pawiri ndi mankhwala formula C2H6S2. Ndi madzi opanda mtundu okhala ndi fungo loipa mwachilendo.
DMDS ili ndi ntchito zosiyanasiyana m'makampani. Choyamba, amagwiritsidwa ntchito ngati chothandizira sulfidation, makamaka m'makampani a petroleum kuti apititse patsogolo ntchito zoyenga ndi njira zina zamafuta. Kachiwiri, DMDS ndi mankhwala ofunika kwambiri ophera tizilombo komanso ophera tizilombo omwe angagwiritsidwe ntchito paulimi ndi ulimi wamaluwa, monga kuteteza mbewu ndi maluwa ku majeremusi ndi tizirombo. Komanso, DMDS chimagwiritsidwa ntchito ngati reagent mu synthesis mankhwala ndi organic kaphatikizidwe zimachitikira.
Njira yayikulu yokonzekera DMDS ndi momwe carbon disulfide ndi methylammonium zimagwirira ntchito. Izi zikhoza kuchitika pa kutentha kwambiri, nthawi zambiri amafuna kugwiritsa ntchito catalysts kuti atsogolere anachita.
Pankhani ya chitetezo, DMDS ndi madzi oyaka komanso onunkhira. Zida zodzitetezera zoyenerera monga magolovesi, magalasi otetezera chitetezo, ndi zovala zodzitetezera ziyenera kuvalidwa pogwira ndi kugwiritsira ntchito. Panthawi imodzimodziyo, iyenera kusungidwa kutali ndi moto ndi magwero otentha kuti ateteze moto kapena kuphulika. Posungirako ndi kunyamula, DMDS iyenera kuikidwa m’chidebe chotsekereza mpweya ndi kusungidwa pamalo ozizira, owuma, opanda mpweya wabwino, kutali ndi zotulutsa okosijeni ndi zoyatsira. Kutuluka mwangozi, njira zochotsera ziyenera kuchitidwa nthawi yomweyo ndipo mpweya wabwino uyenera kutsimikiziridwa.
