    摘要: In chromatographic separation in a plurality of steps with a chromatographic separator packed with an ion exchanger used as at least part of chromatographic packing, at least part of the ionic form of at least part of the ion exchanger is changed to an ionic form fit for separation of components to be separated in each step to effect chromatographic separation, whereby a starting fluid material containing at least 3 components can be efficiently separated into at least 3 fractions. A preferred example of the chromatographic separator comprising a group of packing bed units linked in endless series to form a circulation flow path is provided with a shutoff valve at a position of the circulation flow path; starting fluid material feed means, desorbent feed means and 2-fraction withdrawal means for all the packing bed units; and a single-fraction withdrawal means connected to the circulation flow path on the upstream side of the shutoff valve and without any packing bed unit therebetween.

    摘要: At least 2 different packings differing in the resolution of components contained in a starting fluid material such as a starting solution material and desired to be separated are used in a coexistent state to adjust the resolution of the components. The starting fluid material is flowed through the resultant packing bed to effect chromatographic separation, whereby high-purity fractions enriched with respective components can be obtained at high recoveries with a small amount of desorbent such as eluent. In a chromatographic separator, at least 2 packings comprising a first packing high in the resolution of a component having a medium affinity (affinity for packing) and a weak-affinity component and a second packing high in the resolution of a strong-affinity component and the medium-affinity component in a coexistent state are used as chromatographic packing in contact with a fluid containing the medium-affinity component to adjust the resolution of every two of at least 3 components, whereby at least 3 fractions can be obtained.

    摘要: A starting solution material in the form of waste produced in the course of separation and recovery of sucrose from sugar beet extract or sugar beet molasses with a 2-component separation simulated moving bed chromatographic separator (using a strongly acidic cation exchange resin in a salt form as chromatographic packing) or its concentrate is used to separate therefrom a crude betaine fraction with a 2-component separation simulated moving bed chromatographic separator using as chromatographic packing a strongly acidic cation exchange resin in an ionic form equilibrated with that of the starting solution material. The crude betaine fraction or its concentrate is used to separate therefrom a betaine fraction with a 2-component separation simulated moving bed chromatographic separator using as chromatographic packing a strongly acidic cation exchange resin having at least 10% (based on the ion exchange capacity) of the ionic form thereof changed to the Ca form. The betaine fraction may be concentrated and subjected to crystallization, whereby high-purity betaine can be obtained.

    摘要: Disclosed is a process for producing high-purity glucose by saccharifying liquefied starch with the aid of an enzyme, in which the saccharification reaction of the liquefied starch is discontinued at a point where the glucose content is less than 96% by weight, preferably within the range of 80 to 93% by weight, on a solid basis. The resulting saccharified solution is filtered, concentrated and softened as required, and then fractionated by subjecting it to column chromatography. Thereafter, the resulting glucose fraction is recovered. This process makes it possible to produce high-purity glucose efficiently in spite of a reduction in saccharification time.
