The feasibility of ensuring a wave mode of heat propagation in a mixtu
re of acetylenedicarboxamide (ADCA) and phosphoric anhydride has been
experimentally shown. The limiting concentrations of ADCA, restricting
the occurrence range of the wave process, have been found. The yields
of dicyanoacetylene and by-products obtained in the wave process have
been determined as functions of the concentration of ADCA and initial
temperature of the reaction mixture.
