A process for preparing glucosamine sulfate by electrodialysis technology, using glucosamine hydrochloride and sulfate as the main raw materials, using an electrodialysis device for ion removal or replacement, and innovatively adopting a selective ion membrane to realize the removal of chloride ions And the retention of sulfate ions, the use of bipolar membranes, while removing chloride ions, generates dilute hydrochloric acid that can be used in the process, reducing the release of chlorine and other harmful gases. Through electrodialysis treatment, a crystalline high-purity glucosamine sulfate product can be obtained by further processes such as concentration and crystallization. |
