Abstract
The reactions of cyanogen and cyanogen chloride on copper and oxides of copper have been studied at temperatures between 300 and 375K. The gaseous products were observed to be CO, CO2 and N2. While the surface species are tentatively identified as Cu-C-N and Cu-O-CN (for cyanogen) and Cu-C-N-Cl (for cyanogen chloride). In all cases, even on oxide surfaces, oxygen (ca. E-5 torr) is required for the reaction to proceed to any appreciable extent. It is concluded also that the adsorbed oxygen exchanges with the cyanide ion more readily with cyanogen than with cyanogen chloride.
