Mawu Oyamba
Dimethiomethane (yomwe imadziwikanso kuti methyl sulfide) ndi gulu lachilengedwe. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dimethylthiomethane:
Ubwino:
- Maonekedwe: Madzi opanda mtundu
- Fungo: Lili ndi fungo lamphamvu la hydrogen sulfide
- Kusungunuka: Kusungunuka mu zosungunulira zambiri monga ethanol ndi ether
Gwiritsani ntchito:
- Monga zosungunulira: Dimethiomethane ndi chinthu chofunika kwambiri chosungunulira chomwe chingagwiritsidwe ntchito kusungunula ndi kuyeretsa mankhwala opangidwa ndi organic.
- Chemical synthesis: Nthawi zambiri amagwiritsidwa ntchito ngati reagent komanso wapakatikati mu kaphatikizidwe ka organic, ndipo amatenga nawo gawo mu alkylation, makutidwe ndi okosijeni, sulfidation ndi zina.
- Zida za polima: Dimethylthiomethane itha kugwiritsidwanso ntchito kuphatikizira ndikusintha ma polima.
Njira:
- Dimethylthiomethane ikhoza kupezeka pochita methyl mercaptan ndi dimethyl mercaptan. Pochita, sodium iodide kapena sodium bromide nthawi zambiri amagwiritsidwa ntchito ngati chothandizira.
Zambiri Zachitetezo:
- Dimethylthiomethane ili ndi fungo loipa ndipo imakwiyitsanso maso, khungu ndi thirakiti la kupuma. Magolovesi odzitchinjiriza, magalasi oteteza chitetezo ndi chitetezo cha kupuma ziyenera kuvalidwa zikagwiritsidwa ntchito.
- Pakusunga ndi kunyamula, kukhudzana ndi ma oxidizing amphamvu ndi ma acid kuyenera kupewedwa kuti mupewe zotsatira zoopsa za mankhwala.
- Ikatenthedwa, dimethylthiomethane imatulutsa mpweya wapoizoni (monga sulfure dioxide) ndipo iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino.
- Pogwira ndi kutaya zinyalala, chonde tsatirani malamulo ndi malamulo omwe akukhudzidwa.
