Intangiriro

3,4-Hexanedione (izwi kandi nka 4-Hexanediic Acide) ni ifumbire mvaruganda. Ibikurikira nintangiriro ngufi kumiterere yayo, imikoreshereze, uburyo bwo gukora, namakuru yumutekano:

 

Ubwiza:

- Kugaragara: 3,4-Hexanedione ni kirisiti itagira ibara.

- Gukemura: Gushonga mumashanyarazi kama nkamazi, alcool na ethers.

- Imiterere yimiti: 3,4-hexanedione nuruvange rwa ketone hamwe nubusanzwe bwa ketone. Irashobora kugabanuka kuri diol cyangwa hydroxyketone ihuye, kandi irashobora no kwitwara nka esterification na acylation.

 

Koresha:

- Irashobora kandi gukoreshwa nkibikoresho fatizo byo gutwikira, plastiki, na reberi, ndetse no hagati ya reagent ya chimique na catalizator.

 

Uburyo:

- Hariho uburyo butandukanye bwa synthesis ya 3,4-hexanedione, bumwe muburyo busanzwe bwo gutegura ni ugusuzuma acide formic na propylene glycol kugirango ubone ester ya 3,4-hexanedione, hanyuma ubone ibicuruzwa byanyuma ukoresheje aside hydrolysis.

 

Amakuru yumutekano:

- 3,4-Hexanedione ni uruganda rusange kandi rugomba kwirinda guhura nuruhu, guhumeka cyangwa kuribwa.

- Kwambara ibikoresho bikingira umuntu ku giti cye nka gants, amadarubindi, n'imyambaro ikingira.

- Mugihe cyo kubika no gutunganya, hagomba kwitonderwa inkomoko y’umuriro kandi hagomba kwirindwa guhura n’umuriro, okiside n’ibindi bintu.
