    摘要： The invention relates to sulphonated polymer resins, particularly polymer resins with a sulphonated shell layer, and the preparation thereof. Resins according to the invention are prepared by sulphonating a polymer in a non-swollen state with substantially pure gaseous sulphur trioxide substantially in the shell layer of the polymer particles. The polymer to be sulphonated can be for example a styrene-DVB copolymer. The resins according to the invention can be used for example as chromatographic resins, ion-exchange resins and catalyst resins.

    摘要： The invention relates to a process of recovering galactose from a solution derived from plant-based biomass. In the process of the invention, the starting solution is subjected to one or more chromatographic fractionation steps, which may carried out with a strongly basic anion exchange resin and optionally with a strongly acid cation exchange resin, in any desired sequence, followed by recovering at least one fraction enriched in galactose. The galactose fraction thus obtained is further purified by crystallization to obtain crystalline galactose. The invention also relates to non-animal derived crystalline D-galactose.

    摘要： The present invention relates to a method of fractionating liquid mixtures or solutions, comprising the steps of subjecting a feed in the form of a liquid mixture or solution to a first chromatographic separation, thereby recovering at least a fraction (A) and a fraction (B) both containing a first component or product, subjecting a mixture or solution derived from or comprising said fraction (A) to a second chromatographic separation, thereby recovering at least a fraction (C) rich in said first component or product and subjecting a mixture or solution derived from or comprising said fraction (B) to a third chromatographic separation, thereby recovering at least a fraction (D) also rich in said first component or product, and whereby at least two fractions are recovered from the second and third chromatographic separations.
