Taw qhia
2-Ethyl-3-methylpyrazine yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 2-ethyl-3-methylpyrazine yog nyob rau hauv cov kua xim tsis muaj xim lossis cov khoom crystalline.
- Solubility: Nws muaj tsawg solubility hauv dej, tab sis nws tuaj yeem soluble hauv cov kuab tshuaj organic.
- Stability: Nws yog ib qho chaw ruaj khov, tab sis kev sib cuag nrog cov oxidants muaj zog thiab muaj zog acids yuav tsum raug zam.
Siv:
- 2-Ethyl-3-methylpyrazine yog ib qho reagent uas nquag siv thiab tseem siv los ua ib qho nruab nrab hauv cov tshuaj synthesis.
Txoj kev:
2-Ethyl-3-methylpyrazine tuaj yeem npaj los ntawm cov hauv qab no:
- Ethyl bromide yog thawj zaug nrog pyrazine los tsim 2-ethylpyrazine nyob rau hauv alkaline tej yam kev mob.
- Tom qab, 2-ethylpyrazine yog reacted nrog methyl bromide los muab 2-ethyl-3-methylpyrazine zaum kawg.
Cov ntaub ntawv kev nyab xeeb:
- 2-Ethyl-3-methylpyrazine feem ntau suav hais tias yog cov tshuaj toxicity tsawg, tab sis cov txheej txheem kev nyab xeeb tsim nyog yuav tsum tau ua raws.
- Tsis txhob nqus pa, tiv nrog daim tawv nqaij thiab qhov muag, thiab hnav cov khoom tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab daim npog ntsej muag.
- Thaum khaws cia thiab tuav, khaws cia kom deb ntawm qhov chaw hluav taws xob thiab cov oxidizing cov neeg ua haujlwm kom tsis txhob muaj hluav taws kub thiab tawg.
- Xa mus rau cov ntaub ntawv kev nyab xeeb uas cuam tshuam thiab cov ntaub ntawv kev nyab xeeb uas muab los ntawm tus neeg muag khoom kom paub meej ntxiv thiab raug cov ntaub ntawv kev nyab xeeb.
