Intangiriro

Sodium borohydride nikintu kidasanzwe. Ni ifu ikomeye ishobora gushonga byoroshye mumazi kandi itanga igisubizo cya alkaline.

 

Sodium borohydride ifite imbaraga zo kugabanya kandi irashobora gukora hamwe nibintu byinshi kama. Ikoreshwa cyane muri synthesis organique kandi ikoreshwa kenshi nka hydrogenating agent. Sodium borohydride irashobora kugabanya aldehydes, ketone, esters, nibindi kuri alcool ihuye, kandi irashobora no kugabanya aside kuri alcool. Sodium borohydride irashobora kandi gukoreshwa muri decarboxylation, dehalogenation, denitrification nibindi reaction.

 

Gutegura sodium borohydride mubisanzwe tubona reaction ya borane nicyuma cya sodium. Ubwa mbere, icyuma cya sodiumi gisubizwa hamwe na hydrogène kugirango itegure hydride ya sodium, hanyuma igakorwa na trimethylamine borane (cyangwa triethylaminoborane) muri ether solvent kugirango ibone sodium borohydride.

 

Sodium borohydride nikintu gikomeye kigabanya imbaraga zifata vuba hamwe nubushuhe hamwe na ogisijeni mu kirere kugirango irekure hydrogen. Igikoresho kigomba gufungwa vuba kandi kigakomeza gukama mugihe gikora. Sodium borohydride nayo ikora byoroshye na acide kugirango irekure gaze ya hydrogène, kandi tugomba kwirinda guhura na acide. Sodium borohydride nayo ni uburozi, kandi ugomba kwitondera kwirinda guhumeka cyangwa guhura nuruhu. Mugihe ukoresheje sodium borohydride, ambara uturindantoki turinda ibirahure, hanyuma urebe ko icyo gikorwa gikorerwa ahantu hafite umwuka mwiza.
