Study on synthesis of triethylamine tris(hydrogen fluoride) as fluorinating reagents

Triethylamine tris(hydrogen fluoride) is synthesized,using triethylamine and anhydrous hydrogen fluoride as starting materials and carbon tetrachloride as the solvent.It is a reagent with high boiling point and does not have corrosive action to glass ware,and as fluorinating reagents is widely used for electrochemical selective fluorination of organic compounds.
