| titleOfInvention | The preparation method of a kind of Glucosamine Sulfate Potassium double salt |
| abstract | The present invention relates to the preparation method of a kind of Glucosamine Sulfate Potassium double salt, comprise the steps: (1) dose volume than the water, the tetrahydrofuran (THF) mixing solutions that are 1:10��15; (2) it is warming up to 30��60 DEG C, it is that the sal enixum of 1.0:2.0��2.2, glucosamine hydrochloride add in mixing solutions by mol ratio, stirs 10��20h; (3) it is cooled to 0��5 DEG C, crystallization 3��6h, filters to obtain crystallisate; At 40��60 DEG C, vacuum-drying 0.5��5.0h obtains Glucosamine Sulfate Potassium double salt. The present invention's operation is more simply controlled, is easy to realize, product rate height, easily produces and obtains the brilliant type better product of consistent and uniform degree, it is possible to meets the requirement of pharma grade product; The present invention also have convenient solvent reclaiming, aftertreatment simple, pollute less, the easy advantage such as repetition, suitability for industrialized production. |
