Tetramethylammonium borohydride (CAS# 16883-45-7) chiyambi
Tetramethylammonium borohydride ndi wamba organoboron pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
Tetramethylammonium borohydride ndi kristalo wopanda mtundu wolimba womwe umasungunuka mosavuta m'madzi. Ndi chinthu chamchere chofooka chomwe chimagwirizana ndi zidulo kupanga mchere wofanana. Imamva kutentha ndi kuwala ndipo iyenera kusungidwa pamalo ozizira, owuma.
Gwiritsani ntchito:
Tetramethylammonium borohydride imagwiritsidwa ntchito ngati chothandizira pamachitidwe amankhwala mu organic synthesis. Itha kugwiritsidwa ntchito popanga mankhwala a organoboron, boranes, ndi mankhwala ena. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chochepetsera kuchepetsa ma ayoni achitsulo kapena ma organic mankhwala, ndipo angagwiritsidwe ntchito popanga zitsulo-organic mankhwala.
Njira:
Kukonzekera kwa tetramethylboroammonium hydride nthawi zambiri kumagwiritsa ntchito zomwe methyllithium ndi trimethylborane. Lithium methyl ndi trimethylborane amachita pa kutentha kochepa kupanga lithiamu methylborohydride. Kenako, lithiamu methylborohydride imachitidwa ndi methylammonium chloride kuti ipeze tetramethylammonium borohydride.
Zambiri Zachitetezo:
Tetramethylammonium borohydride ndi yotetezeka ngati ikugwiritsidwa ntchito bwino. Chisamaliro chiyenera kutengedwa kuti musakhudze khungu, maso kapena pakamwa ponyamula kapena pogwira. Izi ziyenera kusungidwa kutali ndi zinthu zomwe zingapse ndi moto ndikusungidwa mu chidebe chotchinga mpweya.
