| Abstract: | The thermal degradation of cellulose and its esters (β-chloropropionate, acetate) in air has been studied by dynamic thermogravimetry and differential thermal analysis from ambient temperature to 600oC. The values of the energy of activation of thermal degradation, Ea , for cellulose and its esters lie in the range 155-225 kJ mol-1. However, the values of free energy of activation for the degradation of cellulose and its esters are almost same and lie in the range 152-185 kJ mol-1. This indicates that the basic step in the thermal degradation of cellulose and its derivatives is the same. IR spectra of the pyrolysis residues of cellulose β-chloropropionate gave indication of dehydration and formation of a compound having C = 0 groups. |
