Thermogravimetric analysis showed that chlorodeoxycellulose is thermally less stable than cellulose. Hydrogen chloride, which is generated from 6-chloro-6-deoxy-D-glucose residues in chlorodeoxycellulose, catalyzed dehydration, condensation and carbonization. The well-known flame resistance of chlorodeoxycellulose was considered to come from these thermal reactions. Pyrolysis products produced by use of a curie-point pyrolyzer were identified. A route of formation of the characteristic products of chlorodeoxycellulose, 5-methyl-2-furaldehyde and 2-furyl methyl ketone, was discussed.
