Abstract

The invention belongs to the technical field of heterogeneous catalysts, and particularly relates to a monodisperse porous organic metal polymer material and a preparation method and application thereof. The polymer is prepared by taking homogeneous double carbene iridium, palladium, gold, copper, cobalt and manganese compounds as monomers and aromatic hydrocarbon as a comonomer in a manner of adding a cross-linking agent and carrying out Friedel-Crafts alkylation under the catalysis of Lewis acid. The polymer can be used for catalyzing hydrogenation cyclization of levulinic acid to prepare gamma-valerolactone, or catalyzing oxidative dehydrogenation of polyol and derivatives thereof and carbohydrate compounds to efficiently prepare lactic acid and derivatives thereof, and dehydrogenationcoupling of alcohol compounds and amine to efficiently prepare pyrrole and derivatives thereof. The polymer material completely holds intrinsic high activity and high selectivity of a homogeneous catalyst precursor and has the characteristics of heterogeneous catalysis stability and easiness in recovery, so that biomass can be converted into various fine chemicals with high efficiency, high selectivity and a large amount; the catalyst can be recycled for multiple times and has a good industrial application prospect.

Description

technical field

[0001] The invention belongs to the technical field of heterogeneous catalysts, and in particular relates to a monodisperse porous organometallic polymer material and its preparation method and application. Background technique

[0002] The development of modern society relies heavily on fossil energy, not only as a source of power energy, but also as a basic raw material for the preparation of bulk chemicals. However, these resources are non-renewable. With the overexploitation of these fossil energy sources, their reserves are gradually depleted. Therefore, it is imminent to seek a green and environmentally friendly renewable resource as a substitute. Biomass is an important part of renewable resources, and the efficient development and utilization of biomass will play a very positive role in solving energy and ecological environment problems. Among them, plant cellulose, lignin, polysaccharide and its downstream product levulinic acid, as important biomas...
