Taw qhia
4-Methylthiazole yog cov organic compound. Cov hauv qab no yog cov lus qhia luv luv rau cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 4-methylthiazole:
Zoo:
- 4-Methylthiazole yog cov xim tsis muaj xim rau lub teeb daj.
- Nws muaj cov ntxhiab tsw ammonia.
- 4-Methylthiazole yog soluble hauv dej thiab feem ntau cov organic solvents ntawm chav tsev kub.
- 4-Methylthiazole yog ib qho tsis muaj zog acidic compound.
Siv:
- 4-Methylthiazole kuj tseem siv rau hauv kev sib txuas ntawm qee yam tshuaj tua kab, xws li thiazolone, thiazolol, thiab lwm yam.
- Nws tseem tuaj yeem siv rau hauv kev tsim cov dyes thiab cov khoom siv roj hmab.
Txoj kev:
- 4-Methylthiazole tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm methyl thiocyanate thiab vinyl methyl ether.
- Thaum lub sij hawm npaj, methyl thiocyanate thiab vinyl methyl ether yog reacted nyob rau hauv alkaline tej yam kev mob los tsim 4-methyl-2-ethopropyl-1,3-thiazole, uas yog ces hydrolyzed kom tau 4-methylthiazole.
Cov ntaub ntawv kev nyab xeeb:
- 4-Methylthiazole yog khaus thiab corrosive thiab tuaj yeem ua rau puas tsuaj rau daim tawv nqaij, qhov muag, thiab ua pa.
- Hnav cov cuab yeej tiv thaiv tsim nyog thaum siv thiab zam kev sib cuag nrog daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus cov pa los yog hmoov av.
- Kev ceev faj yuav tsum tau them rau kev tiv thaiv hluav taws thiab tawg thaum lub sijhawm ua haujlwm thiab khaws cia, thiab kom deb ntawm qhov hluav taws kub thiab oxidants.
- Ua raws li kev tuav pov hwm kev nyab xeeb thiab kev coj ua thaum siv kom tsis txhob muaj kev phom sij.
