Taw qhia

2-Methylbutyric acid. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-methylbutyric acid:

Zoo:

Cov tsos mob: 2-methylbutyric acid yog cov kua tsis muaj xim lossis siv lead ua.

Ceev: approx. 0.92 g / cm³

Solubility: 2-methylbutyric acid yog ib nrab soluble hauv dej.

Siv:

Nws kuj tseem tuaj yeem siv los ua cov kuab tshuaj rau cov resins, plasticizers rau plastics, thiab cov kuab tshuaj rau txheej.

2-Methylbutyric acid kuj tuaj yeem siv rau hauv kev npaj cov hlau xeb inhibitors thiab cov kuab tshuaj pleev xim.

Txoj kev:

Txoj kev npaj ntawm 2-methylbutyric acid yog cov hauv qab no:

Nws yog npaj los ntawm oxidation cov tshuaj tiv thaiv ntawm ethanol.

Npaj los ntawm oxidation cov tshuaj tiv thaiv ntawm 2-methacryrolen.

Cov ntaub ntawv kev nyab xeeb:

2-Methylbutyric acid yog khaus thiab yuav ua rau khaus thiab erythema thaum sib cuag nrog daim tawv nqaij, thiab kev sib cuag ncaj qha ntawm daim tawv nqaij yuav tsum zam.

Kev nqus pa ntawm 2-methylbutyric acid vapor tuaj yeem ua rau mob caj pas, ua pa ua pa, thiab hnoos, thiab yuav tsum tau them nyiaj rau qhov cua thiab tiv thaiv tus kheej.

Thaum siv, kev sib cuag nrog cov oxidants muaj zog thiab combustibles yuav tsum tau zam kom tsis txhob muaj kev phom sij txaus ntshai.

Thaum khaws cia thiab tuav, kev vibration hnyav thiab kub siab yuav tsum tau zam.

Yav dhau los: 3-Methylbutyl 2-Methylbutanoate (CAS # 27627-35-0)

Tom ntej: Ethyl valerate CAS Nr 539-82-2
