Mawu Oyamba

3-Methylpentanoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 3-methylpentanoic acid:

 

Ubwino:

- Maonekedwe: 3-Methylpenteric acid ndi madzi opanda mtundu.

- Kusungunuka: Kusungunuka m'madzi ndi zosungunulira wamba.

- Kununkhira: Kununkhira kowawa koopsa.

 

Gwiritsani ntchito:

- 3-Methylpentanoic acid nthawi zambiri amagwiritsidwa ntchito ngati mankhwala apakatikati pakupanga zinthu zina zakuthupi.

- Itha kugwiritsidwanso ntchito ngati chothandizira pazinthu zina.

 

Njira:

- 3-Methylpenteric acid ikhoza kupezedwa powonjezera polymerization ya propylene carbonate. Methylvaleric anhydride imakumana ndi methacrylenol mu reaction solvent kupanga 3-methylpentanoate. Kenako, 3-methylvaleric acid imachitidwa ndi hydrocyanic acid kuti ipeze 3-methylpentanoic acid.

 

Zambiri Zachitetezo:

- 3-Methylpentanoic acid ndi chokwiyitsa chomwe chingayambitse kuyabwa pakukhudzana ndi khungu ndi maso. Zovala zodzitchinjiriza ndi zoteteza maso ziyenera kuvala mukamagwiritsa ntchito.

- Panthawi yosungira ndikugwiritsa ntchito, ndikofunikira kusunga malo abwino komanso kupewa kukhudzana ndi moto.
