Intangiriro
2,3-Butanedione ni urugimbu. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya 2,3-butanedione:
Ubwiza:
- Kugaragara: 2,3-Butanedione ni amazi atagira ibara afite impumuro nziza.
- Gukemura: Irashobora gushonga mumazi no mumashanyarazi menshi.
- Guhagarara: 2,3-butanedione irahagaze neza kumucyo n'ubushyuhe.
Koresha:
- Gukoresha inganda: 2,3-butanedione ikoreshwa nkibikoresho fatizo byumuti, ibishishwa hamwe ninyongeramusaruro.
- Imyitwarire ya chimique: Irashobora gukoreshwa nkumuhuza wa reaction muri synthesis organique, nka synthesis na okiside ya ketone.
Uburyo:
- Uburyo busanzwe bwa synthesis ni ukubona 2,3-butanedione na okiside ya butanedione. Ibi bigerwaho mugukora 2-butanone hamwe na ogisijeni imbere ya catalizator.
Amakuru yumutekano:
- 2,3-Butanedione irakaze, cyane cyane kumaso no kuruhu. Irinde guhura nuruhu namaso mugihe ukoresheje, hanyuma uhite woza amazi menshi niba hari aho uhurira.
- Ni amazi yaka kandi agomba kwirinda guhura n’amasoko yumuriro kandi agakoreshwa ahantu hafite umwuka mwiza.
- Mugihe habaye gutungurwa kubwimpanuka cyangwa guhumeka, hita witabaza muganga.
