The experiments were performed using equipment which practically excluded deep pyrolysis of the vapor gas products. The hydrogen cyanide was recovered with 0.1 N caustic soda solution in the temperature range of 500 to 1000/sup 0/C. The HCN concentration was measured photometrically by the acid derivative formed as a result of the reaction of the cyanide radical with the barbituric acid amines. The dynamics of the HCN yield were investigated as a function of the heating rate, the degree of comminuition of the coal types and the charge. 2/3 of the HCN is formed as a result of pyrolysis of the vapor-gas products and 1/3 is attributed to the thermochemical conversion of organic matter.
