Procedure

Example 1 was repeated using 1655 g of purified water, 431.5 g (2 moles) of glucosamine hydrochloride and 120.3 g (1 mole) of magnesium sulfate instead of the sodium sulfate. After freeze drying, glucosamine sulfate magnesium chloride was obtained as a white powder in a yield of 530 g (96% of theoretical).
