Procedure

In general, three sources are available for the aqueous mannitol-containing sorbitol solutions used as starting material. One source is derived from invert sugar which is a 50-50 mixture of glucose and fructose which is hydrogenated in the presence of nickel catalysts to form a saturated solution of sorbitol/mannitol in a 3/1 molar ratio. The supernatant liquid remaining after the fractional crystallization of mannitol from the solution normally contains from 7-16 percent mannitol. This mannitol-rich solution can then be dehydrated to form a starting material containing 99.8 percent by weight solids.
