The thermal stability and the kinetics of thermal decomposition of protionamide were studied by thermogravimetry. Activation energy Ea of thermal decomposition of this substance was obtained to be 54.65 kJ·mol-1 by Kissinger method and Ozawa-Flynn-Wall method. Kinetics model function and frequency factor A of protionamide were predicted with the Malek method, which were f(α)=α0.391(1-α)0.145 and lnA=13.12, respectively. Moreover, melting point, molar enthalpy and entropy of fusion of this compound were determined to be 414.09 K, 23.21 kJ·mol-1, and
56.06 J·mol-1·K-1, respectively.
