Abstract: 1,183,162. Dicyanogen. DEUTSCHE GOLDUND - SILBER - SCHEIDEANSTALT. 12 March, 1968 [21 March, 1967], No. 11934/68. Heading C1A. Dicyanogen is produced by reacting cyanogen chloride in the gas phase at above 300‹ C. with silicon or a metal whose chloride has an enthalpy of formation of greater than 97 k. cal. mole or with an alloy of two or more of such elements or with an alloy containing one of such elements as the major constituent. The metal is preferably one whose enthalpy of formation is greater than 105 k. cal. mole . Examples of metals and alloys which may be used are aluminium, titanium, ferrosilicon, silunin and electrum. The reaction is preferably carried out at 500‹ to 1000‹ C.
