%X Thermal stability studies on some metal soaps of Hura crepitans seed oil prepared by metathesis  in aqueous alcohol solution were carried out. The kinetics of the decomposition was studied  thermogravimetrically in the temperature range 160 – 200o C. The values of the rate constant are  of the order 10-2min-1 and temperature-dependent. The enthalpy of activation (ΔH‡) of the initial  stage of decomposition determined is in the range 9.8 – 37.8 kJmol-1. The thermal stability of the  metal soaps was studied in the temperature range 50 – 600o C under nitrogen using  thermogravimetric analyzer (TGA). The thermal stability of the soaps was assessed in terms of  temperatures at which various extents of decomposition were attained and weight loss at the  initial stage of decomposition. Except zinc soap, the weight loss for the metal soaps was less than  10% at temperature up to 250o C. The results suggest that the metal soaps Hura crepitans seed  oils could have some industrial applications.
