Abstract

Thermal analysis of monothiocarbonohydrazones carried out using DTA and TG techniques show that they all decompose exothermally soon after melting. The exothermal decomposition is attributed to the presence of a hydrazino (N-N) bond. The decomposition process has been studied by examining the products of decomposition of benzaldehydethio-carbonohydrazone. Nitrogen, ammonia, hydrogen sulphide, benzonitrile, thiobenzaldehyde, 2,4,6-triphenyl-s-triazine and complex condensation products containing C=N linkages, have been found to be the main products of decomposition. A probable mechanism of decomposition is proposed based on the formation of these products, assuming the homolytic cleavage of the N-N bond as a primary step.
