실험 절차
In accordance with the process described in Example 1, 7.5 kg isomaltulose were dissolved at 80° C. to form a 75% by weight aqueous solution and then transferred to a heated autoclave equipped with an agitator and having a capacity of 20 l. In the autoclave the solution was mixed with an aqueous catalyst suspension containing 500 g Raney nickel. Hydrogenation and crystallization were then carried out as described in Example 1. After a reaction period of 3 hours, the isomaltulose charge had been hydrogenated to form 3.75 kg each of isomaltitol and glucopyranosido-1,6-mannitol. 3.45 kg isomaltitol and 3.45 kg glucopyranosido-1,6-mannitol could then be obtained therefrom in crystal form by means of the fractional crystallization operation described in Example 1.
