Nhanganyaya

Isobutyric acid, inozivikanwawo se2-methylpropionic acid, ndeye organic compound. Iyi inotevera sumo yakadzama kune zvivakwa, mashandisiro, nzira dzekugadzirira uye nekuchengetedza ruzivo rwe isobutyric acid:

Hunhu:

Chitarisiko: Mvura isina ruvara ine kunhuhwirira kwakakosha.

Kuwanda: 0.985 g/cm³.

Solubility: Soluble mumvura uye akawanda organic solvents.

Shandisa:

Zvinyungudutsa: Nekuda kwekunyungudika kwayo kwakanaka, isobutyric acid inoshandiswa zvakanyanya sechinhu chinonyungudutsa, kunyanya mupendi, pendi, nemuchenesi.

Nzira:

Nzira yakajairika yekugadzirira isobutyric acid inowanikwa neoxidation yebutene. Iyi nzira inogadziriswa necatalyst uye inoitwa pakupisa kwakanyanya uye kumanikidzwa.

Zvekuchengetedza

Isobutyric acid ikemikari inoparadza inogona kukonzera kutsamwa uye kukuvadza kana yasangana neganda nemaziso, uye matanho akakodzera anofanira kupfekwa kana uchiishandisa.

Kuratidzwa kwenguva refu kunogona kukonzera kuoma, kuputika, uye kusawirirana.

Paunenge uchichengeta nekubata isobutyric acid, inofanirwa kuchengetedzwa kure nemirazvo yakavhurika uye tembiricha yakakwira kudzivirira moto uye njodzi dzekuputika.
