STUDY ON THE THERMAL-DEGRADATION OF COTTON CELLULOSE AMMONIUM PHOSPHATE AND ITS METAL-COMPLEXES

The thermal degradation of cellulose, and of cellulose ammonium phosph orylate and its metal complex products was studied by thermal analysis , infrared spectroscopy, elemental analysis and chemical analysis. The kinetic parameters were obtained using the equation of Brodio. The va lues of activation energies for decomposition of the cellulose, cellul ose ammonium phosphorylate and its metal complexes were calculated. Ex perimental data for cellulose ammonium phosphorylate and its metal com plexes show that for these samples there is a decrease in the activati on energy for decomposition and an increase in-char yield compared wit h pure cellulose.
