Intangiriro

Furfural, izwi kandi nka 2-hydroxyunsaturated ketone cyangwa 2-hydroxypentanone. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya furfural:

 

Ubwiza:

- Ifite ibara ritagira ibara kandi ifite uburyohe budasanzwe.

- Furfural ifite ubushobozi buke mu mazi, ariko irashobora gushonga muri alcool na ether solver.

- Furfural iroroshye okiside kandi yangirika byoroshye nubushyuhe.

 

Uburyo:

- Uburyo busanzwe bwo gutegura furfural bubonwa na okiside ya C6 alkyl ketone (urugero, hexanone).

- Kurugero, hexanone irashobora okiside kuri furfural ikoresheje ogisijeni na catalizator nka potasiyumu permanganate cyangwa hydrogen peroxide.

- Byongeye kandi, aside aside irashobora kandi gukoreshwa hamwe na alcool zitandukanye za C3-C5 (nka alcool ya isoamyl, nibindi) kugirango ikore ester ihuye, hanyuma igabanuke kugirango ibone furfural.

 

Amakuru yumutekano:

- Furfural ifite uburozi buke ariko iracyakeneye gukoreshwa no kubikwa witonze.

- Irinde guhura nuruhu namaso, hanyuma uhite woza amazi menshi niba aribyo.

- Hagomba kwitonderwa kugirango wirinde guhura na okiside ikomeye, inkomoko yumuriro, nibindi mugihe cyo kubika no gukoresha kugirango wirinde umuriro cyangwa guturika.

- Uburyo bwiza bwo guhumeka bugomba gutangwa mugihe cyo gukoresha kugirango wirinde guhumeka umwuka wumuyaga.
