Intangiriro

2-pentanone, izwi kandi nka pentanone, ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya 2-pentanone:

Ubwiza:

- Kugaragara: 2-pentanone ni ibara ritagira ibara rifite impumuro idasanzwe.

- Gukemura: Irashobora gushonga mumazi kandi nayo ntishobora kuboneka hamwe na solge nyinshi.

- Flammability: 2-pentanone ni amazi yaka umuriro ashobora gutera umuriro mugihe umuriro ufunguye cyangwa ubushyuhe bwinshi.

Koresha:

- Gukoresha inganda: 2-pentanone ikoreshwa nkigishishwa mugukora impuzu, wino, ibifata, nibindi, nkibikoresho byoroshye, byogusukura, hamwe na reaction hagati.

Uburyo:

- 2-pentanone muri rusange itegurwa na okiside pentanol. Uburyo busanzwe ni ukwitwara hamwe na pentanol ukoresheje okiside nka ogisijeni cyangwa hydrogen peroxide, no kwihutisha reaction ya catalizator nka potasiyumu chromate cyangwa cerium oxyde.

Amakuru yumutekano:

- 2-pentanone irashya kandi igomba kubikwa kure yumuriro nubushyuhe bwinshi.

- Kwambara uturindantoki two gukingira, ibirahure birinda, n'ingabo ikingira mu maso kugirango wirinde guhura n'amaso, uruhu, n'umwuka.

- Imyanda igomba kujugunywa hakurikijwe amategeko n'amabwiriza y’ibanze, kandi ntigomba kujugunywa mu mazi cyangwa mu bidukikije.

- Mugihe ubitse kandi ukoresha, nyamuneka ukurikize byimazeyo uburyo bukoreshwa mubikorwa byumutekano hamwe nubuyobozi kugirango umenye neza imikoreshereze yabyo.
