ABSTRACT:
An improved process for the production of cyanogen chloride is disclosed according to which liquid hydrocyanic acid and gaseous chlorine are reacted in an aqueous medium. The liquid hydrocyanic acid and chlorine are introduced into a column-shaped reactor via at least one two-component nozzle. The reaction mixture is removed at the head of the column-shaped reactor. Preferably, the hydrocyanic acid is in liquid form and the chlorine is in gaseous form. By the process disclosed, quantitative yields of cyanogen chloride are obtained separately from aqueous solutions of hydrochloric acid of a strength suitable for commercial use.
