    摘要： PROCESS FOR PARTIAL INTERCONVERSION OF GLUCOSE INTO FRUCTOSE WHICH IS SWEETER THAN THE GLUCOSE BY CONTACTING AN AQUEOUS SOLUTION OF GLUCOSE WITH A MIXTURE OF OR A CONCOMITANT EXISTENCE OF A STRONGLY BASIC ANION EXCHANGE RESIN AND A MODERATELY BASIC ANION EXCHANGE RESIN, BOTH RESINS BEING IN THEIR HYDROXYL FORM, AT A MODERATE TEMPERATURE AND FOR A TIME SUFFICIENT TO ESTABLISH AN EQUILIBRIUM STATE BETWEEN THE GLUCOSE AND FRUCTOSE. BY VIRTUE OF THE CONCOMITANT USE OF THE AFOREMENTIONED RESINS, AN INCREASED CONVERSION VELOCITY OF GLUCOSE INTO FRUCTOSE IS OBTAINED WITHOUT INJURIOUS SIDE REACTION PRODUCTS WHICH WOULD BRING ABOUT CONTAMINATION, COLORATION AND OBJECTIONABLE FLAVOR OF THE FINAL PRODUCT.

    摘要： The invention relates to a method for purifying a mixture to be separated, in a multicolumn chromatography system, the method comprising successively and cyclically:



    a step of collecting a raffinate, a step of injecting the mixture to be separated, a step of collecting an extract and an eluent injection step, at an operating temperature;
    wherein the mixture to be separated has a viscosity at 20° C. greater than or equal to 3 mPa·s; and wherein the dry matter mass concentration of the mixture to be separated is equal, within 5%, to a threshold concentration, said threshold concentration is such that:
    the viscosity of the mixture to be treated at a dry matter mass concentration equal to the threshold concentration and at the operating temperature, is equal to twice the viscosity of the mixture to be treated, at a dry matter mass concentration equal to 85% of the threshold concentration and at the operating temperature.
