Nhanganyaya

2-Methylbutyric acid. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-methylbutyric acid:

 

Hunhu:

Kuonekwa: 2-methylbutyric acid imvura isina ruvara kana kristaro.

Density: approx. 0.92 g/cm³.

Solubility: 2-methylbutyric acid inonyungudika zvishoma mumvura.

 

Shandisa:

Inogona zvakare kushandiswa sechinhu chinonyungudutsa chesimbi, mapurasitiki emapurasitiki, uye zvinonyungudutsa zvekupotera.

2-Methylbutyric acid inogonawo kushandiswa mukugadzirira kwesimbi rust inhibitors uye pendi zvinonyungudutsa.

 

Nzira:

Nzira dzekugadzirira dze2-methylbutyric acid dzinonyanya seizvi:

Iyo inogadzirwa neiyo oxidation reaction ye ethanol.

Yakagadzirirwa ne oxidation reaction ye2-methacryrolen.

 

Zvekuchengetedza

2-Methylbutyric acid inogumbura uye inogona kukonzera kutsamwa uye erythema kana inosangana neganda, uye kusangana kwakananga neganda kunofanira kudziviswa.

Inhalation ye2-methylbutyric acid vapor inogona kukonzera kushatirwa kwehuro, kutsamwa kwekufema, uye kukosora, uye kutarisisa kunofanirwa kubhadharwa kumhepo uye kuchengetedzwa kwemunhu.

Panguva yekushandiswa, kusangana neakasimba oxidants uye zvinopisa zvinofanirwa kudziviswa kudzivirira kuita kune njodzi.

Paunenge uchichengetedza uye uchibata, kuzununguka kwakanyanya uye kupisa kwakanyanya kunofanira kudziviswa.
