Procedure

Glucosamine sulfate sodium chloride was prepared by the following procedure. A one-liter, three-necked flask equipped with a thermometer, stirrer, heating mantle and condenser was charged with 1720 g of purified water and 431.5 g (2.0 moles) of glucosamine hydrochloride. The glucosamine hydrochloride promptly went into solution, with stirring (the dissolution of the glucosamine hydrochloride was endothermic in nature). After stirring for a few minutes, 142 g (1.0 mole) of sodium sulfate was added to the solution and stirring was continued for about one hour at 35-40° C. to complete the reaction.
