Abstract: Cyanogen halides, particularly cyanogen bromide and cyanogen chloride, are prepared in an electrolysis cell with cathode and anode chambers separated by a semi-permeable diaphragm, by reacting halide ions with hydrogen cyanide or a salt thereof in the anode chamber by means of a direct current, the pH value of the reactant in the anode chamber being lower than 4.

Abstract: An improved process and apparatus for preparing cyanuric chloride by trimerizing cyanogen chloride in the presence of chlorine. The cyanogen chloride is produced by electrolytically reacting a solution of hydrogen cyanide or a salt thereof with chloride ion in an anode chamber of an electrolytic cell at a pH of less than 4.
