I-Tetramethylammonium borohydride (CAS# 16883-45-7) intshayelelo
I-Tetramethylammonium borohydride yinto eqhelekileyo ye-organoboron compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
I-Tetramethylammonium borohydride yinto eqinileyo yekristale engenambala nenyibilika lula emanzini. Yinto ebuthathaka yealkaline edibana neeasidi zenze iityuwa ezihambelanayo. Inochuku kukukhanya nobushushu kwaye kufuneka igcinwe kwindawo epholileyo neyomileyo.
Sebenzisa:
I-Tetramethylammonium borohydride isetyenziswa ngokuqhelekileyo njenge-catalyst kwi-chemical reactions in organic synthesis. Ingasetyenziswa kwi-synthesis ye-organoboron compounds, i-boranes, kunye nezinye iikhompawundi. Ukongeza, inokusetyenziswa njenge-arhente yokunciphisa ukunciphisa i-ion zetsimbi okanye i-organic compounds, kwaye ingasetyenziselwa ukudibanisa i-metal-organic compounds.
Indlela:
Ukulungiswa kwe-tetramethylboroammonium hydride ngokuqhelekileyo isebenzisa ukusabela kwe-methyllithium kunye ne-trimethylborane. I-lithium methyl kunye ne-trimethylborane zisabela kumaqondo obushushu aphantsi ukwenza i-lithium methylborohydride. Emva koko, i-lithium methylborohydride iphendulwa nge-methylammonium chloride ukufumana i-tetramethylammonium borohydride.
Ulwazi ngoKhuseleko:
I-Tetramethylammonium borohydride ikhuselekile phantsi kweemeko eziqhelekileyo zokusetyenziswa. Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nesikhumba, amehlo okanye umlomo xa uphethe okanye uphathwa. Kufuneka igcinwe kude nemithombo yomlilo kunye nezinto ezinokutsha kwaye igcinwe kwisitya esingangeni moya.
