Hordhac

2-Methylbutyric acid. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada ee 2-methylbutyric acid:

 

Tayada:

Muuqaalka: 2-methylbutyric acid waa dareere aan midab lahayn ama crystal.

Cufnaanta: qiyaastii. 0.92 g/cm³.

Solubility: 2-methylbutyric acid waxay qayb ahaan ku milmi kartaa biyaha.

 

Isticmaal:

Waxa kale oo loo isticmaali karaa sida dareere loogu talagalay resins, caagadaha caagga ah, iyo dareerayaasha dahaarka.

2-Methylbutyric acid waxa kale oo loo isticmaali karaa diyaarinta biraha daxalaystayaasha iyo dareerayaasha rinjiga.

 

Habka:

Hababka diyaarinta ee 2-methylbutyric acid inta badan waa sida soo socota:

Waxaa lagu diyaariyaa falcelinta oksaydhka ee ethanol.

Waxaa diyaariyey falcelinta oksaydhka ee 2-methacryrolen.

 

Macluumaadka Badbaadada:

2-Methylbutyric acid waa cuncun waxayna keeni kartaa cuncun iyo erythema marka maqaarka la taabto, waana in laga fogaado taabashada tooska ah ee maqaarka.

Neefsashada uumiga 2-methylbutyric acid wuxuu keeni karaa cunaha cuncun, cuncun xagga neefsashada ah, iyo qufac, waana in fiiro gaar ah loo yeesho hawo-qaadista iyo ilaalinta shakhsi ahaaneed.

Inta lagu jiro isticmaalka, xiriirka oksidants xooggan iyo gubasho waa in laga fogaadaa si looga hortago falcelinta khatarta ah.

Marka kaydinta iyo maaraynta, gariirka daran iyo heerkulka sare waa in laga fogaadaa.
