Procedure

Example 1 was repeated using 1855 g of purified water, 431.5 g (2 moles) of glucosamine hydrochloride and 287.5 g (1 mole) of zinc sulfate (heptahydrate) instead of the sodium sulfate. After freeze drying, glucosamine sulfate zinc chloride was obtained as a white powder in a yield of 540 g (95% of theoretical).
