Tetrabutylammonium cyanoborohydride

white crystalline powder

Put 339.5 kg of tetrabutylammonium hydrogen sulfate into the reaction kettle, add 50 kg of water, and start stirring to make it evenly mixed. Add 14 kg sodium hydroxide aqueous solution (5%) at room temperature. In addition, 69.3 kg of sodium cyanoborohydride was dissolved in 40 kg of water to form a solution, added to the reaction kettle, stirred for 0.5 to 1 h, then extracted with an organic solvent, and left to stand to separate the lower layer. The organic phase is transferred to a water washing kettle, washed with water, decolorized, filtered, the filtrate is concentrated, cooled and crystallized, and recrystallized with ethyl acetate to obtain a pure product.

Used as a selective reducing agent in organic synthesis.
