Tetramethylammonium borohydride (CAS # 16883-45-7) Kev taw qhia
Tetramethylammonium borohydride yog ib hom organoboron compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Tetramethylammonium borohydride yog cov xim tsis muaj xim crystalline uas yooj yim soluble hauv dej. Nws yog ib qho tsis muaj zog alkaline uas ua rau cov kua qaub los tsim cov ntsev sib xws. Nws yog rhiab heev rau lub teeb thiab cua sov thiab yuav tsum tau khaws cia rau hauv qhov chaw txias, qhuav.
Siv:
Tetramethylammonium borohydride feem ntau yog siv los ua cov tshuaj tiv thaiv hauv cov tshuaj lom neeg hauv cov organic synthesis. Nws tuaj yeem siv rau hauv kev sib txuas ntawm organoboron tebchaw, boranes, thiab lwm yam tebchaw. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua tus neeg saib xyuas kom txo tau cov hlau ions lossis cov organic sib txuas, thiab tuaj yeem siv los ua cov hlau-organic compounds.
Txoj kev:
Kev npaj ntawm tetramethylboroammonium hydride feem ntau yog siv cov tshuaj tiv thaiv ntawm methyllithium thiab trimethylborane. Lithium methyl thiab trimethylborane reacts ntawm qhov kub thiab txias los tsim lithium methylborohydride. Tom qab ntawd, lithium methylborohydride yog reacted nrog methylammonium chloride kom tau tetramethylammonium borohydride.
Cov ntaub ntawv kev nyab xeeb:
Tetramethylammonium borohydride kuj muaj kev nyab xeeb nyob rau hauv ib txwm siv. Yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij, qhov muag lossis qhov ncauj thaum nqa lossis tuav. Nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab cov khoom siv hluav taws xob thiab khaws cia rau hauv ib lub thawv airtight.
