摘要：
Method for preparing a compound comprising protonated glucosamine and Cl<；SUP>；-<；/SUP>；, Na<；SUP>；+<；/SUP>； and SO<；SUB>；4<；/SUB>；<；SUP>；2-<；/SUP>； ions, in which (a) glucosamine hydrochloride and a stoichiometric excess of sodium sulphate are placed in water, (b) the mixture obtained from the preceding step (a) is heated, (c) the mixture is cooled, and (d) the solid present in the said cooled mixture is recovered by filtration. Compound comprising protonated glucosamine and Cl<；SUP>；-<；/SUP>；, Na<；SUP>；+<；/SUP>； and SO<；SUB>；4<；/SUB>；<；SUP>；2-<；/SUP>； ions and having the X-ray diffraction diagram of FIG. 1.
