Hordhac

2,3-Butanedione waa unug dabiici ah. Kuwa soo socdaa waa horudhac ku saabsan guryaha, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada 2,3-butanedione:

 

Tayada:

- Muuqashada: 2,3-Butanedione waa dareere aan midab lahayn oo leh ur jilicsan.

- Solubility: Waxay ku milmaysaa biyaha iyo dareerayaal badan oo organic ah.

- Xasilooni: 2,3-butanedione waa mid xasiloon iftiinka iyo kulaylka.

 

Isticmaal:

Codsiyada warshadaha: 2,3-butanedione waxaa inta badan loo isticmaalaa sida alaabta ceeriin ee dareeraha, dahaarka iyo wax lagu daro caag ah.

- Falcelinta kiimikaad: Waxaa loo isticmaali karaa dhexdhexaadinta falcelinta ee isku-dhafka dabiiciga ah, sida isku-dhafka iyo oksaydhka ketones.

 

Habka:

- Habka isku-dhafka caadiga ah waa in la helo 2,3-butanedione by oksidation of butanedione. Tan waxaa lagu gaaraa iyada oo la falcelinayo 2-butanone oo leh ogsijiin iyadoo ay jirto joogitaanka kicinta.

 

Macluumaadka Badbaadada:

- 2,3-Butanedione waa xanaaq, gaar ahaan indhaha iyo maqaarka. Ka fogow taabashada maqaarka iyo indhaha marka la isticmaalayo, oo isla markiiba ku luqluq biyo badan haddii ay jirto xiriir.

- Waa dareere guban kara, waana in laga fogaadaa in lala taabto ilaha dabka oo loo isticmaalo meel hawo fiican leh.

- Haddii ay dhacdo in si lama filaan ah u nuugto ama neefsato, u raadi daryeel caafimaad isla markiiba.
