Nhanganyaya

Sodium borohydride is anorganic compound. Ihupfu hwakasimba hunonyungudika nyore nyore mumvura uye hunogadzira alkaline solution.

 

Sodium borohydride ine simba rekudzikisa zvivakwa uye inogona kuita neakawanda organic komisheni. Inoshandiswa zvakanyanya mu organic synthesis uye inowanzoshandiswa sehydrogenating agent. Sodium borohydride inogona kuderedza aldehydes, ketones, esters, nezvimwewo kune zvinwiwa zvinodhaka, uye inogonawo kuderedza maasidhi kune doro. Sodium borohydride inogona zvakare kushandiswa mu decarboxylation, dehalogenation, denitrification uye mamwe maitiro.

 

Kugadzirira kwe sodium borohydride kunowanzo kuwanikwa nekuita kweborane uye sodium simbi. Kutanga, simbi yesodium inobatwa nehydrogen kugadzirira sodium hydride, uye yozoita ne trimethylamine borane (kana triethylaminoborane) mu ether solvent kuti iwane sodium borohydride.

 

Sodium borohydride isimbi yakasimba yekudzikisa iyo inobata nekukurumidza nehunyoro uye oksijeni mumhepo kuburitsa haidrojeni. Iyo mudziyo unofanirwa kuvharwa nekukurumidza uye ugare wakaoma panguva yekushanda. Sodium borohydride inobatawo zviri nyore nemaasidhi kuburitsa hydrogen gasi, uye kusangana nemaasidhi kunofanirwa kudzivirirwa. Sodium borohydride zvakare ine muchetura, uye kutarisirwa kunofanirwa kutorwa kudzivirira kufemerwa kana kubata ganda. Paunenge uchishandisa sodium borohydride, pfeka magirovhosi ekudzivirira uye magirazi, uye ona kuti kuvhiya kunoitwa munzvimbo ine mhepo inofefetera.
