TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The step (B) and/or (C) are carried out during stirring. The reaction temperature in step (B) and (C) is maintained at 0-5 degrees C. The mixed salt is separated from the reaction mixture by filtration and washed with a washing solution comprising the non-aqueous solvent used in step (A) and water. The weight ratio between the non-aqueous solvent and water in the washing solution is 3-2 to 3-1 (preferably 3-1). The washed mixed salt is further washed with an additional washing solution essentially consisting of the non-aqueous solvent. Under step (A) one part by weight of glucosamine hydrochloride is suspended in 2-3 parts by weight of the non-aqueous solvent. The molar ratio of the basic alkali metal salt to glucosamine hydrochloride is less than 1.2-2 (preferably less than 1.05-2, especially 1-2). The weight ratio of the basic alkali metal salt to water is 1-0.5 to 1-1.5. The molar ratio of alkali metal hydrogen sulfate to glucosamine hydrochloride is less than 1.2-2 (preferably less than 1.05-2, especially 1-2). In step (C), the weight ratio of alkali metal hydrogen sulfate to water is 1-0.75 to 1-1.5. Preferred Components: The basic alkali metal salt is sodium salt and/or potassium salt (preferably sodium acetate and/or potassium acetate). The alkali metal hydrogen sulfate is sodium hydrogen sulfate and/or potassium hydrogen sulfate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The non-aqueous solvent is an alcohol (preferably methanol and/or ethanol). EXAMPLE - In a reaction vessel, ethanol (178 g) and glucosamine hydrochloride (75 g) were charged and during stirring, the suspension was cooled to 0-5 degrees C. Potassium acetate (17.06 g) was dissolved in water (9 ml) and the resulting clear solution was then slowly added to the reaction vessel over a period of 20-30 minutes. On complete addition of the potassium acetate solution, the direct reaction pH measured was 7.88 and the pH of the reaction mixture sample diluted in 6 parts water was 5.90. Potassium hydrogen sulfate (23.68 g) was dissolved in water (36 ml) and the clear solution was then added slowly to the reaction vessel over a period of 30-40 minutes and stirring was continued for further 30 minutes, while the temperature of reaction was maintained at 0-5 degrees C. At this stage, on direct measurement the pH of the reaction mixture was 2.8 and the pH of the reaction mixture sample diluted with 6 parts water was 3.2. The product was then separated by filtration. The wet cake of glucosamine sulfate potassium chloride was washed three times with 75% ethanol in water solution followed by a final wash with ethanol. Washed solids were dried at 40-45 degrees C under vacuum. The yield of snow white glucosamine sulfate potassium chloride was 100.3 g (95.25%). The glucosamine base content by colorimetric estimation was 99.58%, the chloride assay by HPLC was 100.7%, and the specific optical rotation was 50.3 degrees . The absorbance value (at 280 nm) and % transmittance value (at 450 nm) were 0.12 and 98.12%, respectively.
