Abstract
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.
