Mawu Oyamba
4,5-Dimethylthiazole ndi organic pawiri. Nazi zina mwazinthu zake, ntchito, njira zopangira, ndi chidziwitso chachitetezo:
Ubwino:
- Maonekedwe: Madzi opanda mtundu kapena olimba a crystalline.
- Kusungunuka: Kusungunuka mu zosungunulira zambiri monga ma alcohols, ethers ndi ketones.
- Kukhazikika: Ndi yokhazikika pa kutentha kwa chipinda.
Gwiritsani ntchito:
- Itha kugwiritsidwanso ntchito ngati chothamangitsira mphira komanso chowotcha mphira kuti chiwongolere zida zamakina a rabara.
Njira:
- 4,5-Dimethylthiazole ikhoza kupangidwa ndi zomwe dimethyl sodium dithiolate ndi 2-bromoacetone.
- Rection equation: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.
Zambiri Zachitetezo:
- 4,5-Dimethylthiazole ndi organic pawiri ndipo ayenera kupewedwa ndi miyeso yoyenera kusamalira.
- Magolovesi oteteza, magalasi ndi magalasi amafunikira mukamagwiritsa ntchito.
- Pewani kutulutsa nthunzi yake ndikuwonetsetsa kuti ikugwira ntchito pamalo abwino mpweya wabwino.
- Pakachitika ngozi mwangozi m'maso, yambani nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala mwachangu.
- Sungani 4,5-dimethylthiazole pamalo ozizira, owuma kutali ndi okosijeni ndi zidulo zamphamvu.
