Taw qhia

Methyl butyrate. Cov hauv qab no yog kev qhia txog qee yam khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm methyl butyrate:

 

Zoo:

- Methyl butyrate yog cov kua nplaum uas tsis muaj dej-soluble.

- Nws muaj solubility zoo, soluble hauv cawv, ethers thiab qee cov kuab tshuaj organic.

 

Siv:

- Methyl butyrate feem ntau yog siv los ua cov kuab tshuaj, plasticizer thiab diluent hauv txheej txheej.

- Nws kuj tseem siv tau los ua ib qho nruab nrab hauv cov organic synthesis rau kev npaj ntawm lwm cov tebchaw.

 

Txoj kev:

- Methyl butyrate tuaj yeem npaj los ntawm reacting butyric acid nrog methanol nyob rau hauv acidic tej yam kev mob. Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no:

CH3COO + CH3OH → CH3COOCH2CH2CH3 + H2O

- Cov tshuaj tiv thaiv feem ntau yog ua los ntawm cua sov nrog cov catalyst (xws li sulfuric acid lossis ammonium sulfate).

 

Cov ntaub ntawv kev nyab xeeb:

- Methyl butyrate yog cov kua hluav taws xob uas tuaj yeem hlawv thaum raug hluav taws kub, kub kub, lossis cov organic oxidants.

- Kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab kub hnyiab, yuav tsum tau ceev faj.

- Methyl butyrate muaj qee yam toxicity, yog li nws yuav tsum tau zam rau kev nqus pa thiab tsis siv neeg, thiab siv nyob rau hauv qhov cua zoo.

- Kev saib xyuas yuav tsum tau coj los tiv thaiv kev sib cuag nrog oxidants, acids thiab alkalis thaum siv lossis khaws cia.
