    摘要： This invention is a process for the chromatographic separation of a fluid mixture in which the mixture is contacted with an ion-exchange resin, eluted through the resin under conditions such that the rate of passage of one component of the mixture through the resin bed is retarded relative to the rate of passage of a second component of the mixture, and a first product stream rich in said first component and a second product stream rich in said second component are recovered. The invention involves the use of an ion-exchange resin made from a copolymer which is prepared in a multi-stage polymerization process. The use of this resin is found to provide fast separation kinetics and increases the overall speed and efficiency of the separation. This invention is particularly suited for fructose/glucose separations in the preparation of high fructose corn syrup.

    摘要： The present invention is a process for the chromatographic separation of a liquid mixture comprising a first sugar component and at least one secondary component chosen from second sugars, organic acids and salts thereof, alcohols, amino acids, and inorganic salts. In the process, the liquid mixture is contacted with a stratum of a porous gel cation-exchange resin and thereafter eluted such that the first sugar component passes through the stratum at a different rate relative to the secondary components of the liquid mixture. The separation results in a first recoverable product stream rich in the first sugar component and at least one secondary product stream rich in the secondary components. The porous gel cation-exchange resin is prepared by polymerization of at least one monovinylidene monomer with a cross-linking monomer in the presence of an inert diluent. The use of such porous gel resins in the process increases kinetics, improves yields of desired sugar components, and results in a more efficient separation process. The invention is particularly applicable to separation of glucose from fructose in the preparation of high fructose corn syrup.
