Intangiriro
Potasiyumu borohydride nikintu kidasanzwe. Imiterere yacyo niyi ikurikira:
1. Kugaragara: Potasiyumu borohydride ni ifu yera ya kirisiti cyangwa granule.
3. Gukemura: Potasiyumu borohydride irashobora gushonga mumazi hanyuma igahinduka buhoro buhoro mumazi kugirango itange hydrogène na hydroxide ya potasiyumu.
4. Uburemere bwihariye: Ubucucike bwa potasiyumu borohydride ni 1,1 g / cm³.
5. Guhagarara: Mubihe bisanzwe, potasiyumu borohydride irahagaze neza, ariko irashobora kubora imbere yubushyuhe bwinshi, ubuhehere bwinshi na okiside ikomeye.
Imikoreshereze nyamukuru ya potasiyumu borohydride irimo:
1. Inkomoko ya hydrogène: Potasiyumu borohydride irashobora gukoreshwa nka reagent ya synthesis ya hydrogen, ikorwa no gufata amazi.
2. Imiti igabanya imiti: potasiyumu borohydride irashobora kugabanya ibice bitandukanye byingirakamaro kama nka alcool, aldehydes, na ketone.
3. Gutunganya ibyuma byubutaka: Potasiyumu borohydride irashobora gukoreshwa mugutunganya hydrogène hydrogène hydrogène yo hejuru yicyuma kugirango igabanye okiside yo hejuru.
Uburyo bwo gutegura potasiyumu borohydride ikubiyemo uburyo bwo kugabanya mu buryo butaziguye, uburyo bwa antiborate nuburyo bwo kugabanya ifu ya aluminium. Muri byo, uburyo bukoreshwa cyane buboneka kubisubizo bya sodium phenylborate na hydrogen munsi ya catalizator.
Amakuru yumutekano ya potasiyumu borohydride niyi ikurikira:
1. Potasiyumu borohydride ifite kugabanuka gukomeye, kandi hydrogène ikorwa iyo ifashe amazi na aside, bityo ikaba igomba gukorerwa ahantu hafite umwuka mwiza.
2. Irinde guhura nuruhu, amaso, ninzira zubuhumekero kugirango wirinde kurakara no gukomeretsa.
3. Iyo ubitse kandi ukoresha potasiyumu borohydride, ugomba kwitonda kugirango wirinde guhura na okiside nibindi bintu kugirango wirinde umuriro cyangwa guturika.
4. Ntukavange potasiyumu borohydride nibintu bya aside kugirango wirinde ko habaho imyuka mibi.
5. Iyo utaye imyanda ya potasiyumu borohydride, hagomba gukurikizwa amabwiriza ajyanye n’ibidukikije n’umutekano.
