Method for preparing D-erythrose from biomass saccharides

Abstract

The invention belongs to the technical field of biomass conversion and chiral synthesis and particularly relates to a method for preparing D-erythrose from biomass saccharides. According to the invention, the biomass saccharides are adopted as the raw materials, and under the aqueous phase condition and the alkaline environment, the raw materials are catalyzed to obtain the D-erythrose. The method is has the following characteristics: the type of the biomass saccharides is more, the initial concentration range of the biomass saccharides is wide, the heating manner is flexible, the basicity range of a catalyst is wide, and the single chirality of the catalyst is realized; the operation is simple and convenient, equipment is simple, energy is saved, the aftertreatment is convenient, and both the percent conversion and the selectivity are high. As the D-erythrose is regarded as one of important platform chemical compounds at present, a series of products with wide application ranges can be obtained through chiral conversion and achiral conversion, can serve as midbodies of fine chemical engineering and pharmacy, and has huge economical value and broad application prospects. Therefore, through the method for efficiently preparing a great amount of D-erythrose from the biomass saccharides, large-scale industrialized production is expected to realize.

Description

technical field [0001] The invention belongs to the field of biomass technology and chiral synthesis, and in particular relates to a method for preparing D-erythrose. Background technique [0002] D-erythrose is a four-carbon sugar with reducing aldehyde groups, containing two adjacent chiral carbon atoms. Free erythrose has not been found in nature, and it is generally produced by oxidation of calcium D-arabinate have to. D-erythrose-4-phosphate is an intermediate in the enzymatic conversion of carbohydrates. D-Erythrose is an organic compound containing two adjacent chiral carbon atoms. If the configuration is equivalent to the chiral carbon atom of erythrose, the compound is called red configuration. [0003] Chirality is the basic characteristic of life process, and most of the organic molecules that make up living organisms are chiral molecules. Most of the drugs used by people have chirality and are called chiral drugs. The "mirror image" of a chiral drug is called...
