Thermolysis of anhydrous, amorphous, acidified sucrose results in polymerization initially involving the fructosyl cation and later the glucosyl cation. Monomeric and dimeric anhydro sugars form during the thermolysis and are incorporated into the fructoglucan polymer.
We have reinvestigated temperature effects on the rates of hydrolysis of 0.0585M sucrose in 0.57M HCl solutions over the range of 10-40°C using polarimetry as a physical method to follow the reaction while simultaneously analyzing the solutions by HPLC for the disappearance of sucrose and by GLC for
Recent interest in the measurement and the interpretation of heat capacities of activation has led to more rigorous methods to detect temperature-varient activation parameters. One such method devised by Blandamer and co-workers was applied to the sucrose hydrolysis data of Moelwyn-Hughes and Leinin
