Sucrose → Sucrose

Reaction Conditions

Reaction Steps

100 g of sucrose are added to 233 g of water and the aqueous solution is cooled to a temperature of 4° C. 5.6 g of calcium hydroxide are added to form a sucrose/calcium hydroxide adduct corresponding to a mole ratio of sucrose to calcium hydroxide of 1:0.25. Gaseous carbon dioxide is then bubbled through the adduct solution at a rate of 700 ml/min until the pH drops from an initial value of 12.1 to a value of 9.4. The total time of the reaction is 20 minutes. The reaction medium is then quick frozen by means of dry ice and freeze-dried in a manner similar to that set forth in Example I.
