Taw qhia

4-Methylvaleric acid, tseem hu ua isovaleric acid, yog cov organic compound. Cov hauv qab no yog cov lus qhia luv luv txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: Soluble nyob rau hauv dej thiab organic solvents

- Cov ntxhiab tsw: muaj qaub aroma zoo li acetic acid

 

Siv:

- Hauv kev lag luam tshuaj tsw qab, nws tuaj yeem siv los ua cov khoom qab zib ntawm txiv hmab txiv ntoo, zaub thiab khoom qab zib.

- Hauv kev lag luam coatings, nws yog siv los ua cov kuab tshuaj thiab plasticizer.

 

Txoj kev:

- 4-Methylpentanoic acid tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm isovaleric acid thiab carbon monoxide nyob rau hauv lub xub ntiag ntawm lub teeb.

- Catalysts xws li aluminic acid los yog potassium carbonate feem ntau siv rau hauv cov tshuaj tiv thaiv.

 

Cov ntaub ntawv kev nyab xeeb:

- 4-Methylpentanoic acid yog cov nplaim hluav taws kub thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab kub kub.

- Hnav cov khoom tiv thaiv tsim nyog, xws li hnab looj tes thiab qhov muag tiv thaiv, thaum siv.

- Tsis txhob nqus pa, noj, lossis tiv nrog daim tawv nqaij thiab qhov muag thaum tuav.
