Description
Technical Field
The invention belongs to the technical field of heterogeneous catalytic materials, and particularly relates to a preparation method of covalent organic framework material loaded copper ions for replacing phosphomolybdic acid, and cyclooctene and cyclododecene epoxidation reaction are catalyzed.
Background
The epoxy compound is an important intermediate product with wide application in chemical industry, and is widely applied to the fields of medicines, materials, chemical industry and the like. Olefin epoxidation reaction is a main source for producing epoxy compounds, wherein methods such as a halohydrin method and a peracid method are used for synthesizing the olefin epoxy compounds, but the used oxidant has the problems of environmental pollution, equipment corrosion, complex production, low yield, high energy consumption and the like. To ameliorate the above problems, many emerging catalysts have been developed for olefin epoxidation. CN110433826A utilizes a coprecipitation method to prepare a single-atom gold catalyst for catalyzing the epoxidation reaction of styrene by taking air as an oxidant. Although the catalytic performance is good and the stability is good, the gold is expensive and the energy consumption is high; CN110694676A discloses a mesoporous catalyst of TUD-1 doped with lanthanide metal, which can catalyze C in alkyl hydrogen peroxide solution3-C10An alkene or cycloalkene of (a). The preparation process of the catalyst is complex and takes a long time, which is not beneficial to industrial production.
Heteropolyacids are oxygen-containing polyacid green catalysts composed of heteroatoms (such as P, Si, Fe, Co, etc.) and polyatomic atoms (such as Mo, W, V, Nb, Ta, etc.). Because of the unique acidity, quasi-liquid phase behavior, and multiple functions of heteropoly acids, they are widely regarded by researchers in the field of catalytic research and olefin epoxidation. CN106975522A develops a phosphomolybdotungstic heteropoly acid catalyst and catalyzes olefin epoxidation reaction by taking tert-butyl hydroperoxide as an oxidant, wherein the tert-butyl hydroperoxide pollutes the environment and has higher energy consumption.
The invention utilizes cheap and easily-obtained transition metal copper substituted Keggin type phosphomolybdic heteropoly acid to prepare the olefin epoxidation catalyst PCuMo with excellent performance11@ PC, this catalyst can utilize oxygen direct catalysis cyclooctene and cyclododecene, and the preparation process of catalyst is simple, low in production cost and catalysis process green have popularization and application and worth.
