Embodiment example 1

[0017] Add 100mg glucose, 10mol% catalyst, 3ml dimethyl sulfoxide to 10ml micro reaction tube, react at 120°C for 2h, after the reaction ends. The content was determined by HPLC. The conversion rate of glucose: 86.7%, the yield of fructose: 13.9%.

Embodiment example 2

[0019] Add 100mg glucose, 10mol% catalyst, 2ml N,N-dimethylacetamide to a 10ml micro-reaction tube, react at 140°C for 2h, after the reaction is over. The content was determined by HPLC. The conversion rate of glucose was 78.8%, and the yield of fructose: 23.8%.

Embodiment example 3

[0021] Add 100mg glucose, 10mol% catalyst, 1.5ml dimethyl sulfoxide, 0.5ml water to 10ml micro-reaction tube, react at 140°C for 3h, after the reaction ends. The content was determined by HPLC. The conversion rate of glucose was 88.4%, and the yield of fructose: 30.1%.

Abstract

The invention discloses a preparation method of a metal complex containing a mesoporous material MCM-41 schiff-base ligand and application of the metal complex, and belongs to the field of environment-friendly purification. The chemical component of the metal complex is Cr-Sal-EDA-MCM-41; and a structural formula is as shown in the drawing of the abstract. The metal complex containing the mesoporous material MCM-41 schiff-base ligand disclosed by the invention is simple in synthesis condition, and diverse in coordination structure, and has relatively good oxygen-carrying capacity, metalloenzyme-simulating catalytic action, and relatively good catalytic conversion action of catalytic biomass. The mesoporous material chromium metal complex has relatively large specific surface area, relatively large aperture and a lot of high-activity surface hydroxyl groups; assembly of organic active groups in holes and full contact of reactants and active sites are facilitated; and the catalytic activity is improved.

Description

technical field [0001] The invention relates to a chromium complex containing a mesoporous material MCM-41 Schiff base ligand and its preparation method and application, specifically, a preparation of a complex formed by a metal and an MCM-41 Schiff base ligand Methods and applications in catalytic conversion of biomass. Background technique [0002] With the sharp increase of energy consumption, the decrease of fossil resources, the aggravation of energy crisis and the continuous deterioration of ecological environment, the sustainable development of human beings is seriously threatened. Biomass is the most abundant renewable resource on the earth. It is non-polluting, renewable and widely distributed. Therefore, the use of biomass resources to produce biofuels and high value-added fine chemical products has broad development prospects and practical significance. [0003] Mesoporous material MCM-41 has the characteristics of good hydrothermal stability due to its large spe...
