Okwu mmalite

Sodium borohydride bụ ngwakọta inorganic. Ọ bụ ntụ ntụ siri ike nke na-agbaze ngwa ngwa na mmiri ma na-emepụta ngwọta alkaline.

 

Sodium borohydride nwere ikike ibelata siri ike ma nwee ike meghachi omume na ọtụtụ ogige organic. A na-eji ya eme ihe n'ọtụtụ ebe na njikọ organic ma na-ejikarị ya dị ka onye na-emepụta hydrogenating. Sodium borohydride nwere ike ibelata aldehydes, ketones, esters, wdg na mmanya ndị kwekọrọ, ma nwee ike belata acid na mmanya. A pụkwara iji sodium borohydride mee ihe na decarboxylation, dehalogenation, denitrification na mmeghachi omume ndị ọzọ.

 

Nkwadebe nke sodium borohydride na-enwetakarị site na mmeghachi omume nke borane na sodium metal. Nke mbụ, a na-emeghachi metal sodium na hydrogen iji dozie sodium hydride, wee meghachi omume na trimethylamine borane (ma ọ bụ triethylaminoborane) na ether ihe mgbaze iji nweta sodium borohydride.

 

Sodium borohydride bụ ihe na-ebelata ike nke na-eme ngwa ngwa na mmiri na ikuku oxygen na-ahapụ hydrogen. Ekwesịrị mechie akpa ahụ ngwa ngwa ma debe ya mgbe ọ na-arụ ọrụ. Sodium borohydride na-emeghachikwa omume ngwa ngwa site na acid iji hapụ hydrogen gas, na ekwesịrị izere kọntaktị na acid. Sodium borohydride bụkwa ihe na-egbu egbu, ekwesịrị ịkpachara anya ka ị ghara ikuku ume ma ọ bụ mmetụ akpụkpọ ahụ. Mgbe ị na-eji sodium borohydride, yiri gloves nchebe na ugogbe anya, ma hụ na a na-arụ ọrụ ahụ na ebe ikuku na-ekpo ọkụ.
