Mawu Oyamba

4-Methylvaleric acid, yomwe imadziwikanso kuti isovaleric acid, ndi organic pawiri. Zotsatirazi ndizofotokozera mwachidule za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

 

Ubwino:

- Maonekedwe: Madzi opanda mtundu

- Kusungunuka: Kusungunuka m'madzi ndi zosungunulira za organic

- Kununkhira: Kununkhira kowawa kofanana ndi asidi

 

Gwiritsani ntchito:

- M'makampani onunkhira, atha kugwiritsidwa ntchito kupanga zokometsera za zipatso, ndiwo zamasamba ndi zokometsera.

- M'makampani opanga zokutira, amagwiritsidwa ntchito ngati zosungunulira ndi plasticizer.

 

Njira:

- 4-Methylpentanoic acid ikhoza kukonzedwa ndi zomwe isovaleric acid ndi carbon monoxide pamaso pa kuwala.

- Zothandizira monga aluminium acid kapena potaziyamu carbonate nthawi zambiri zimagwiritsidwa ntchito pochita.

 

Zambiri Zachitetezo:

- 4-Methylpentanoic acid ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri.

- Valani zida zodzitetezera zoyenera, monga magolovesi ndi zoteteza maso mukamagwiritsa ntchito.

- Pewani kutulutsa mpweya, kumeza, kapena kukhudza khungu ndi maso mukamagwira ntchito.
