Mawu Oyamba

2 - methylbutyric acid. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-methylbutyric acid:

 

Ubwino:

Maonekedwe: 2-methylbutyric acid ndi madzi opanda mtundu kapena kristalo.

Kachulukidwe: pafupifupi. 0.92g/cm³.

Kusungunuka: 2-methylbutyric acid imasungunuka pang'ono m'madzi.

 

Gwiritsani ntchito:

Itha kugwiritsidwanso ntchito ngati chosungunulira cha utomoni, mapulasitiki opangira mapulasitiki, ndi zosungunulira zokutira.

2-Methylbutyric acid itha kugwiritsidwanso ntchito popanga zitsulo zoletsa dzimbiri komanso zosungunulira utoto.

 

Njira:

Njira zokonzekera za 2-methylbutyric acid makamaka ndi izi:

Imakonzedwa ndi makutidwe ndi okosijeni a Mowa.

Wokonzeka ndi makutidwe ndi okosijeni anachita 2-methacryrolen.

 

Zambiri Zachitetezo:

2-Methylbutyric acid imakwiyitsa ndipo imatha kuyambitsa kuyabwa ndi erythema ikakhudzana ndi khungu, ndipo kukhudzana mwachindunji ndi khungu kuyenera kupewedwa.

Kukoka mpweya wa 2-methylbutyric acid kungayambitse kupsa mtima kwapakhosi, kupuma movutikira, komanso kutsokomola, ndipo chidwi chiyenera kuperekedwa ku mpweya wabwino komanso chitetezo chamunthu.

Mukamagwiritsa ntchito, kukhudzana ndi ma okosijeni amphamvu ndi zoyaka moto kuyenera kupewedwa kuti mupewe zoopsa.

Posunga ndi kusamalira, kugwedezeka kwakukulu ndi kutentha kwakukulu kuyenera kupewedwa.
