A kind of purification process for the more glucose sodium that relaxes

The invention discloses a kind of purification process of more glucose sodium that relaxes, includes the following steps: 1) to be put into a part of cation exchange resin and be impregnated in the suspension or solution of metal hydroxides or metal salt, rinse, obtain transition ion exchange resin A;Another part cation exchange resin is placed into aqueous solution soaking that is stand-by or being put into sodium hydroxide simultaneously, is rinsed, transition ion exchange resin B is obtained;2) more glucose sodium crude product is relaxed under the processing of transition ion exchange resin A, correspondingly it is converted to the easypro more glucose salt that solubility in water is less than the more glucose sodium that relaxes, it is purified through hot beating, the more glucose sodium that relaxes is converted to by transition ion exchange resin B again, or after being handled by cation exchange resin, then through sodium hydroxide change into relax more glucose sodium.Method provided by the invention can significantly improve the purity for the more glucose sodium that relaxes, and reduce the difficulty of purifying products, and have to the impurity in crude product and remove effect well, this method has good economy, is more suitable for industrialized production.
