Cation Exchange Process for the Preparation of Potassium Cyanide

Abstract

Equihbrium data are presented for the react,ons of Na + KCN, KC1 -~-NaCN, and KOt{ + NaCN ,n the fused state The latter two reactmns were effected by a new "alloy bridge" technique which does not require d,rect contact of reactant salts In this mannm. potassium cyanl(te was obtained substant,ally free of anmns other than CN-. Reacinon rate d~ta are plesented for reactmn of KC1 + NaCN by the "alloy bridge" method, and other poss,ble apphcations of the method are suggested.
