Mawu Oyamba

N-valeric acid, yomwe imadziwikanso kuti valeric acid, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha n-valeric acid:

Ubwino:

N-valeric acid ndi madzi opanda mtundu okhala ndi kukoma kwa zipatso ndipo amasungunuka m'madzi.

Gwiritsani ntchito:

N-valeric acid imakhala ndi ntchito zosiyanasiyana m'makampani. Ntchito imodzi yayikulu ndi monga zosungunulira m'mafakitale monga zokutira, utoto, zomatira, ndi zina.

Njira:

Valeric acid ikhoza kukonzedwa ndi njira ziwiri zofala. Njira imodzi ndikuthira oxidize pentanol ndi mpweya pamaso pa chothandizira kupanga n-valeric acid. Njira ina ndiyo kukonzekera n-valeric acid mwa oxidizing 1,3-butanediol kapena 1,4-butanediol ndi mpweya pamaso pa chothandizira.

Zambiri Zachitetezo:

Norvaleric acid ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi malawi otseguka ndi magwero a kutentha. Pogwira ndikugwiritsa ntchito, ndikofunikira kutenga njira zodzitetezera, monga kuvala magalasi oteteza, magolovesi oteteza komanso zovala zodzitchinjiriza. N-valeric acid iyeneranso kusungidwa mu chidebe chopanda mpweya, kutali ndi okosijeni ndi zakudya. Chisamaliro chiyenera kutengedwa posunga ndi kugwiritsa ntchito kuti musagwirizane ndi mankhwala ena.
