摘要： Embodiments of the present disclosure provide a method for preparing a high-purity arabinose crystal, comprising operations of dissolving, blending, ion exchange, decolorization and filtration, fine filtration, evaporation and concentration, crystallization, centrifugation, and drying performed in sequence on a low-purity arabinose crystal. Throughout the operations of preparing the arabinose crystal, a pH value of a material may be controlled between 4.3 and 7.5, and a temperature may not exceed 70° C. This prevents arabinose from transforming into impurities under a high temperature, thereby maintaining and improving a purity of the prepared arabinose crystal.

摘要： The invention relates to a continuous method for obtaining a crystalline monosaccharide, comprising: continuous crystallization of the monosaccharide in a main crystallizer (10), wherein crystallization by evaporation and/or crystallization by cooling is carried out continuously on a crystal suspension in the main crystallizer in order to allow crystals of the monosaccharide to grow in the crystal suspension; separation of crystals of the monosaccharide out of the crystal suspension to obtain crystalline monosaccharide; continuous formation of a mass of crystallization magma for the main crystallizer (10) in a cascade, wherein the cascade comprises at least one first stage (13) and a final stage (15) connected in series and each stage comprises at least one pre-crystallizer (13A, 15A), wherein, in the at least one pre-crystallizer (13A) of the first stage (13), a solution is seeded with monosaccharide by means of monosaccharide seed crystals in order to obtain a pre-crystallization magma, and a mass of crystallization magma for the downstream stage (14, 15) is formed from the pre-crystallization magma by means of crystallization by cooling and/or crystallization by evaporation, and wherein a solution containing monosaccharide and a mass of crystallization magma from the upstream stage is supplied to the at least one pre-crystallizer (15A, 15B, 15C) of the final stage (15) to obtain a pre-crystallization magma, and in the at least one pre-crystallizer (15A, 15B, 15C) of the final stage (15) a mass of crystallization magma for the main crystallizer (10) is formed from the pre-crystallisation magma by means of crystallization by cooling and/or crystallization by evaporation; the continuous supply of a solution containing the monosaccharide and a mass of crystallization magma from the at least one pre-crystallizer (15A, 15B, 15C) of the final stage (15) of the cascade to the main crystallizer (10) to provide the crystal suspension.

摘要： This invention provides a method for producing a glycan with improved yield ratio of streocontrolled glycan. Additionally it provides the building blocks used as the sugar donor and as the sugar acceptor to implement a method for producing the glycan. It also provides a novel compound. It subjects the specific building block A of this invention to electrolytic oxidation in an aprotic organic solvent that contains an electrolyte; and subjects the specific building block B of this invention to glycosylation with the electrolytically oxidized building block A in the method for producing a glycan based on the liquid phase process.

摘要： Disclosed herein is a class of chiral binuclear metal complexes for stereoselective hydrolysis of saccharides and glycosides, and more particular chiral binuclear transition metal complex catalysts that discriminate epimeric glycosides and α- and β-glycosidic bonds of saccharides in aqueous solutions at near physiological pHs. The chiral binuclear metal complexes include a Schiff-base-type ligand derived from a chiral diamino building block, and a binuclear transition metal core, each which can be varied for selectivity. The metal core is a Lewis-acidic metal ion, such as copper, zinc, lanthanum, iron and nickel. The Schiff-base may be a reduced or non-reduced Schiff-base derived from aliphatic linear, aliphatic cyclic diamino alcohols or aromatic aldehydes. The ligand can be a penta- or heptadentate ligand derived from pyridinecarbaldehydes, benzaldehydes, linear or cyclic diamines or diamino alcohols.
