Mawu Oyamba

Dimethyl sulfide (yomwe imadziwikanso kuti dimethyl sulfide) ndi gulu la sulfure wachilengedwe. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dimethyl sulfide:

Ubwino:

- Maonekedwe: Madzi opanda mtundu okhala ndi fungo lapadera lamphamvu.

- Kusungunuka: kusakanikirana ndi ethanol, ethers, ndi zosungunulira zambiri za organic.

Gwiritsani ntchito:

- Ntchito zamafakitale: Dimethyl sulfide imagwiritsidwa ntchito kwambiri ngati zosungunulira mu organic synthesis reaction, makamaka muzochita za sulfidation ndi thioaddition.

Njira:

- Dimethyl sulfide imatha kukonzedwa ndi zomwe ethanol ndi sulfure zimachita. Zomwe zimachitika nthawi zambiri zimachitika pansi pa acidic ndipo zimafunikira kutentha.

- Itha kukonzedwanso powonjezera sodium sulfide ku ma methyl bromides awiri (monga methyl bromide).

Zambiri Zachitetezo:

- Dimethyl sulfide imakhala ndi fungo loyipa ndipo imawononga khungu ndi maso.

- Pewani kukhudza khungu ndi maso ndipo samalani mukamagwiritsa ntchito.

- Mukamagwiritsa ntchito ndikusunga, kukhudzana ndi okosijeni ndi ma acid amphamvu kuyenera kupewedwa kuti mupewe zovuta.

- Zinyalala zikuyenera kutayidwa motsatira malamulo ndi malamulo a mderalo ndipo zisamatayidwe.

- Sungani mpweya wabwino panthawi yosungira ndikugwiritsa ntchito.

Zam'mbuyo: 2-Acetyl thiazole (CAS#24295-03-2)

Ena: Furfuryl methyl sulfide (CAS#1438-91-1)
