実験手順

Example 1 was repeated using 1679 g of purified water, 431.5 g (2 moles) of glucosamine hydrochloride and 128 g (1 mole) of lithium sulfate (monohydrate) instead of the sodium sulfate. After freeze drying, glucosamine sulfate lithium chloride was obtained as a white powder in a yield of 525 g (97% of theoretical).
