Tetramethylammonium borohydride (CAS# 16883-45-7) sumo
Tetramethylammonium borohydride inowanzoitika organoboron compound. Inotevera sumo kune hunhu hwayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
Tetramethylammonium borohydride icrystalline solid isina ruvara inonyungudika mumvura zviri nyore. Chinhu chisina kusimba chealkaline chinopindirana nemaasidhi kuita munyu unoenderana. Inonzwa chiedza nekupisa uye inofanira kuchengetwa munzvimbo inotonhorera, yakaoma.
Shandisa:
Tetramethylammonium borohydride inowanzoshandiswa sechinhu chinokonzeresa mukuchinja kwemakemikari mune organic synthesis. Inogona kushandiswa mukugadzirwa kweorganoboron compounds, boranes, uye mamwe makomisheni. Pamusoro pezvo, inogona zvakare kushandiswa sechinhu chinodzikisira kudzikisa simbi ions kana organic komisheni, uye inogona kushandiswa kugadzira simbi-organic makomisheni.
Nzira:
Kugadzirira kwe tetramethylboroammonium hydride kunowanzo shandisa maitiro emethyllithium uye trimethylborane. Lithium methyl uye trimethylborane inobata pane yakadzika tembiricha kuti iite lithium methylborohydride. Zvadaro, lithium methylborohydride inobatwa ne methylammonium chloride kuti iwane tetramethylammonium borohydride.
Zvekuchengetedza
Tetramethylammonium borohydride inenge yakachengeteka pasi pemamiriro ekushandiswa. Kuchengetedza kunofanira kutorwa kuti usasangana neganda, maziso kana muromo paunenge uchitakura kana kubata. Inofanira kuchengetedzwa kure nemoto uye zvinhu zvinopisa uye inochengetwa mumudziyo usina mhepo.
