Taw qhia

Ethyl butyrate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ethyl butyrate:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Nplej: Champagne thiab fruity sau ntawv

- Solubility: Soluble nyob rau hauv organic solvents, insoluble nyob rau hauv dej

 

Siv:

- Cov kuab tshuaj: dav siv los ua cov kuab tshuaj organic hauv kev lag luam xws li txheej, varnishes, inks thiab adhesives.

 

Txoj kev:

Kev npaj ntawm ethyl butyrate feem ntau yog ua los ntawm esterification. Acidic acid thiab butanol reacted nyob rau hauv lub xub ntiag ntawm acid catalysts xws li sulfuric acid los tsim ethyl butyrate thiab dej.

 

Cov ntaub ntawv kev nyab xeeb:

- Ethyl butyrate feem ntau suav hais tias yog tshuaj lom neeg muaj kev nyab xeeb, tab sis yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no:

- Tsis txhob nqus cov pa los yog cov pa roj thiab ua kom qhov chaw ua haujlwm tau zoo.

- Tsis txhob kov daim tawv nqaij thiab yaug tam sim nrog dej yog tias nws kov daim tawv nqaij.

- Zam kev noj tshuaj tsis haum, thiab nrhiav kev kho mob tam sim yog tias noj tsis raug.

- Khaws kom deb ntawm qhov hluav taws kub thiab kub, khaws cia, thiab tsis txhob sib cuag nrog oxidants.
