Hordhac

N-valeric acid, oo sidoo kale loo yaqaan valeric acid, waa unug dabiici ah. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada ee n-valeric acid:

 

Tayada:

N-valeric acid waa dareere aan midab lahayn oo leh dhadhan miro leh oo ku milmay biyaha.

 

Isticmaal:

N-valeric acid waxay leedahay adeegyo kala duwan oo loo isticmaalo warshadaha. Mid ka mid ah codsiga ugu weyn waa sida dareeraha warshadaha sida dahaarka, midabada, xabagta, iwm.

 

Habka:

Valeric acid waxaa lagu diyaarin karaa laba hab oo caadi ah. Mid ka mid ah hababka ayaa ah in qayb ahaan oxidize pentanol iyo oksijiin ay jirto joogitaanka kicinta si loo soo saaro n-valeric acid. Hab kale ayaa ah in la diyaariyo n-valeric acid iyadoo oxidizing 1,3-butanediol ama 1,4-butanediol oo leh oksijiin iyadoo ay jirto koronto.

 

Macluumaadka Badbaadada:

Norvaleric acid waa dareere guban kara waana in laga fogeeyo ololka furan iyo meelaha kulaylka. Marka la maaraynayo oo la isticmaalayo, waa lagama maarmaan in la qaado tallaabooyinka ilaalinta lagama maarmaanka ah, sida xidhashada muraayadaha ilaalinta, galoofyada ilaalinta iyo dharka ilaalinta. N-valeric acid sidoo kale waa in lagu kaydiyaa weel aan hawadu lahayn, kana fog oksidayaasha iyo alaabta cuntada. Waxa loo baahan yahay in taxaddar la sameeyo marka la kaydinayo lana isticmaalayo si looga fogaado falcelinta kiimikooyinka kale.
