Nhanganyaya

Isovaleric asidhi. Inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza isovaleric acid:

Hunhu:

Chitarisiko: Mvura isina ruvara kana yero ine kunhuhwirira kwakafanana neacetic acid.

Density: 0.94g/cm³

Solubility: inonyungudika mumvura, inogona zvakare kusanganiswa ne ethanol, ether uye mamwe organic solvents.

Shandisa:

Synthesis: Isovaleric acid yakakosha kemikari synthesis yepakati, iyo inoshandiswa zvakanyanya muminda yakawanda yemaindasitiri senge organic synthesis, mishonga yemishonga, coating, rabha nemapurasitiki.

Nzira:

Iyo nzira yekugadzirira ye isovaleric acid inosanganisira nzira dzinotevera:

Kuburikidza neiyo oxidation reaction yen-butanol, iyo oxidation yen-butanol kune isovaleric asidhi inoitwa pachishandiswa acidic catalyst uye oxygen.

Magnesium butyrate inoumbwa nekuita kwe magnesium butyl bromide ine carbon dioxide, iyo inobva yashandurwa kuita isovaleric acid nekuita ne carbon monoxide.

Zvekuchengetedza

Isovaleric acid chinhu chinoparadza, dzivisa kusangana neganda nemaziso, uye teerera kushandiswa kwemagetsi ekudzivirira, magirazi ekuchengetedza uye zvipfeko zvekudzivirira.

Paunenge uchishandisa isovaleric acid, inhalation yehuputi hwayo inofanira kudziviswa uye kushanda kunofanira kuitwa munzvimbo ine mhepo yakanaka.

Nzvimbo yekubatidza yakadzikira, dzivisa kusangana nenzvimbo yemoto, uye chengetedza kure nemirazvo yakavhurika uye zvinopisa.

Muchiitiko chekusangana netsaona kune isovaleric acid, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa.

Zvakapfuura: Methyl p-tert-butylphenylacetate (CAS#3549-23-3)

Zvinotevera: Diethylsuccinate (CAS#123-25-1)
