Tetramethylammonium borohydride (CAS# 16883-45-7) horudhac
Tetramethylammonium borohydride waa unug ka kooban organoboron. Kuwa soo socdaa waa hordhac dabeecadeeda, isticmaalkeeda, hababka wax-soo-saarka iyo macluumaadka badbaadada:
Tayada:
Tetramethylammonium borohydride waa crystalline adag oo aan midab lahayn oo si fudud ugu milmay biyaha. Waa walax alkaline ah oo daciif ah oo la falgasha asiidh si ay u sameeyaan milix u dhigma. Waxay u nugul tahay iftiinka iyo kuleylka waana in lagu hayaa meel qabow oo qallalan.
Isticmaal:
Tetramethylammonium borohydride waxaa badanaa loo isticmaalaa kicinta falcelinta kiimikaad ee isku-dhafka organic. Waxaa loo isticmaali karaa isku-dhafka organoboron, boranes, iyo xeryahooda kale. Intaa waxaa dheer, waxa kale oo loo isticmaali karaa sida wakiilka yaraynta yaraynta ion birta ama xeryahooda organic, iyo waxaa loo isticmaali karaa in ay synthesize biraha-organic xeryahooda.
Habka:
Diyaarinta tetramethylboroammonium hydride caadi ahaan waxay isticmaashaa falcelinta methyllithium iyo trimethylborane. Lithium methyl iyo trimethylborane waxay ka falceliyaan heerkul hooseeya si ay u sameeyaan lithium methylborohydride. Kadibna, lithium methylborohydride waxaa lagu falceliyaa methylammonium chloride si loo helo tetramethylammonium borohydride.
Macluumaadka Badbaadada:
Tetramethylammonium borohydride waa mid badbaado leh marka loo eego xaaladaha caadiga ah ee isticmaalka. Waa in taxaddar la sameeyaa si looga fogaado taabashada maqaarka, indhaha ama afka marka la qaadayo ama la qabanayo. Waa in laga fogeeyaa ilaha dabka iyo walxaha guban oo lagu kaydiyo weel hawo-mareen ah.
