Taw qhia

N-acetylglycine 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 N-acetylglycine:

 

Zoo:

- N-acetylglycine yog dawb crystalline khoom uas yog soluble hauv dej thiab ethanol. Nws yog acidic hauv kev daws.

 

Siv:

 

Txoj kev:

- N-acetylglycine feem ntau yog npaj los ntawm reacting glycine nrog acetic anhydride (acetic anhydride). Cov tshuaj tiv thaiv yuav tsum tau ua nyob rau hauv acidic tej yam kev mob thiab yog ua tau los ntawm cua sov.

- Hauv chav kuaj, acetic anhydride tuaj yeem siv los ua cov tshuaj glycine thiab lwm yam tshuaj, thiab cov khoom tuaj yeem ua kom huv los ntawm crystallization los ntawm cua sov nyob rau hauv lub xub ntiag ntawm acidic catalyst.

 

Cov ntaub ntawv kev nyab xeeb:

- Nws feem ntau suav tias muaj kev nyab xeeb thaum siv kom raug. Cov tib neeg tuaj yeem ua xua rau N-acetylglycine thiab yuav tsum tau kuaj kom zoo rau kev ua xua ua ntej siv. Cov lus qhia tsim nyog rau kev siv yuav tsum tau ua raws thiab cov khoom siv yuav tsum tau siv kom tsim nyog.
