Intangiriro
2,3-dimethyl-2-butene (DMB) ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
Kugaragara: DMB ni amazi atagira ibara.
Gukemura: Irashobora gushonga mumashanyarazi menshi nka Ethanol, ethers, na hydrocarbone.
Ubucucike: Ubucucike bwayo bugera kuri 0,68 g / cm³.
Uburozi: DMB ntabwo ifite uburozi, ariko guhura cyane birashobora gutera uburibwe bwamaso no kurwara uruhu.
Koresha:
Synthesis ya chimique: DMB isanzwe ikoreshwa muri synthesis organique nkigisubizo, hagati, cyangwa catalizator.
Inganda zikomoka kuri peteroli: DMB nayo ikoreshwa nkimiti yingenzi ikoreshwa mugutunganya peteroli ya jute no gutunganya peteroli.
Uburyo:
DMB isanzwe itegurwa na alkylation ya methylbenzene na propylene. Intambwe zihariye zirimo gukora methylbenzene na propylene kubushyuhe bukwiye hamwe nigitutu imbere ya catalizator yo kubyara DMB.
Amakuru yumutekano:
Nkumusemburo kama, DMB irahinduka. Mugihe cyo gukoresha, birakenewe gukomeza guhumeka neza no kwirinda guhura cyane.
Birashobora gutera uburakari mugihe uhuye nuruhu namaso. Guhura igihe kirekire, guhumeka, cyangwa kumira bigomba kwirindwa.
Mugihe cyo kubika no gutunganya DMB, hagomba kwirindwa reaction hamwe na okiside ikomeye na acide ikomeye.
Mugihe uhuye niyi ngingo, hita woza ahantu h'uruhu cyangwa amaso yanduye n'amazi menshi hanyuma ushakire kwa muganga.
