| Abstract: | The mechanism and kinetics of the thermal decomposition reaction of Bombyx-mori cocoons are studied by means of the TGA and IR me- thods.On the basis of the thermal traces of four different content linear heating rates,the activation energies for the thermal decomposition of 5_,10_,and 15_percent are calculated to be 410.8-,376.7_,and 324.0_ kj/mol respectively.The mechanism of the reaction is derived from the IR of the residue and gaseous products of the decomposition. |
