Hydrothermal decomposition of NaCN, Na<sub>2</sub>[Zn(CN)<sub>4</sub>] and Na<sub>3</sub>[Cu(CN)<sub>4</sub>] (particulary, Na<sub>2</sub>[Cu(CN)<sub>3</sub>]) in aqueous solution using a batch-type autoclave was investigated at the temperature range of 373K to 423K, under pressurized condition of 1 MPa. The initial CN concentration in the sample solution was set at 1g dm<sup>−3</sup>. As a results, it was found that the rate of CN decomposition in NaCN solution increased with an increase in the temperature. The decomposition rate was found to be expressed by first-order reaction kinetics. For the metal cyanide complexes, the rate of CN decomposition increased in the following order Cu < Zn < Na, which was attributed to a decrease in the stability constant of metal cyanide complexes in the same order. It was recognized that the reaction products of formic acid, ammonia, and carbonate were formed in the decomposition of NaCN and Na<sub>2</sub>[Zn(CN)<sub>4</sub>] in the experimental condition.By contrast, formic acid, ammonia, carbonate, nitrous acid, and nitrogen were produced by the decomposition of Na<sub>3</sub>[Cu(CN)<sub>4</sub>]. Furthermore, it was found that the metal ions of Cu and Zn were precipitated as insoluble CuO and ZnO, respectively.<br>
