Note 49 — Chapter IX · COMPOUNDS OF CARBON WITH OXYGEN AND NITROGEN
George Kamensky translation
Cyanogen (like chlorine) is absorbed by a solution of sodium hydroxide, sodium cyanide and cyanate being produced: C2N2 + 2NaHO = NaCN + CNNaO + H2O. But the latter salt decomposes relatively easily, and moreover part of the cyanogen liberated by heat from its compounds undergoes a more complex transformation.
