Taw qhia
2-Acetyl-3-ethylpyrazine yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw:
Khoom: 2-acetyl-3-ethylpyrazine yog cov xim tsis muaj xim crystalline nrog cov qauv tshwj xeeb nitrogen heterocyclic. Nws muaj kev ruaj ntseg siab thiab tsis-volatility ntawm chav tsev kub. Nws yog yooj yim soluble nyob rau hauv ib co organic solvents thiab tsawg soluble nyob rau hauv dej.
Siv: 2-acetyl-3-ethylpyrazine muaj ntau yam kev siv hauv cov organic synthesis. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob zoo rau ntau yam tseem ceeb ntawm cov organic, xws li carbonylation, oxidation, thiab amination.
Txoj kev npaj: Muaj ntau txoj hauv kev los npaj 2-acetyl-3-ethylpyrazine, thiab txoj kev siv feem ntau yog tau los ntawm reacting acetylformamide thiab 3-ethylpyrazine. Tshwj xeeb, acetoformamide thiab 3-ethylpyrazine yog thawj zaug sib xyaw, rhuab nyob rau hauv cov xwm txheej tsim nyog, thiab tom qab ntawd cov khoom lag luam tau txais los ntawm crystallization thiab purification.
Nws tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab ua pa, thiab cov cuab yeej tiv thaiv tsim nyog xws li tsom iav, hnab looj tes, thiab lub ntsej muag tiv thaiv yuav tsum hnav thaum ua haujlwm. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog nqus tau cov tshuaj no, ntxuav los yog nrog kws kho mob tam sim ntawd.
