Thermohydrolytic degradation

Interaction of Chain Destruction and Cross-linking in Thermal and Thermohydrolytic Degradation of Cellulose. Starting points of these investigations were the statement of a thermal level-off-DP by Golova and Krylova (10) and observations of our own (8) of an increase...

Influence of Cellulose Physical Structure on Thermohydrolytic, Hydrolytic, and Enzymatic Degradation of Cellulose... 

The initial rate of chain-length degradation AS/At, with S = 1/DP (Table II), increased, of course, with degradation temperature, both in the thermal and the thermohydrolytic treatments of the linters, but the Arrhenius energy of activation was much lower in thermohydrolysis. The difference in the rate between both kinds of treatment decreased significantly after a decrystallizing pretreatment of the linters with liquid... 

Invulnerability of the oxidation component to O2 attack and, under these conditions, stability of the imide cycle, preserved even in degradation products, eliminates the thermohydrolytic mechanism, discussed in the literature.
