Nhanganyaya

N-valeric acid, inozivikanwawo se valeric asidhi, inhengo yeorganic. Iyi inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza n-valeric acid:

 

Hunhu:

N-valeric acid imvura isina ruvara ine fruity flavour uye inonyungudika mumvura.

 

Shandisa:

N-valeric acid ine zvakasiyana-siyana zvekushandisa muindasitiri. Chimwe chikuru chekushandisa chakaita sechinhu chinonyungudutsa mumaindasitiri akadai semachira, madhayi, zvinonamira, nezvimwe.

 

Nzira:

Valeric acid inogona kugadzirwa nenzira mbiri dzakajairika. Imwe nzira ndeyekuita zvishoma oxidize pentanol uye oksijeni muhupo hwechigadziriso chekugadzira n-valeric acid. Imwe nzira ndeyekugadzirira n-valeric acid ne oxidizing 1,3-butanediol kana 1,4-butanediol neokisijeni muhupo hwekugadzirisa.

 

Zvekuchengetedza

Norvaleric asidhi imvura inopfuta uye inofanirwa kuchengetedzwa kure nemirazvo yakavhurika nekupisa. Pakubata nekushandisa, zvinodikanwa kutora matanho ekudzivirira anodiwa, sekupfeka magirazi ekudzivirira, magirovhosi ekudzivirira uye zvipfeko zvekudzivirira. N-valeric acid inofanirawo kuchengetwa mumudziyo usina mhepo, kure neoxidants uye zvinhu zvekudya. Kuchengetedza kunoda kutorwa paunenge uchichengeta uye uchishandisa kudzivirira kusangana nemamwe makemikari.
