Intangiriro

Cyclohexanone nikintu kama. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya cyclohexanone:

 

Ubwiza:

- Kugaragara: Amazi atagira ibara afite impumuro nziza.

- Ubucucike: 0,95 g / cm³

- Gukemura: Gushonga mumashanyarazi kama nkamazi, Ethanol, ether, nibindi.

 

Koresha:

- Cyclohexanone ni umusemburo ukoreshwa cyane mugukuramo ibishishwa no gukora isuku mu nganda zikora imiti nka plastiki, reberi, amarangi, nibindi.

 

Uburyo:

- Cyclohexanone irashobora gutangizwa na cyclohexene imbere ya ogisijeni kugirango ikore cyclohexanone.

- Ubundi buryo bwo kwitegura ni ugutegura cyclohexanone ukoresheje decarboxylation ya acide caproic.

 

Amakuru yumutekano:

- Cyclohexanone ifite uburozi buke, ariko biracyakenewe kuyikoresha neza.

- Irinde guhura nuruhu namaso, wambare uturindantoki two kurinda na gogles.

- Tanga umwuka mwiza mugihe ukoreshejwe kandi wirinde guhumeka cyangwa kuribwa.

- Mugihe ufashwe kubwimpanuka cyangwa guhura cyane, shakisha ubufasha bwihuse.

- Mugihe ubitse kandi ukoresha cyclohexanone, witondere ingamba zo gukumira umuriro no guturika, kandi ubibike kure yumuriro nubushyuhe bwinshi.
