Abstract

The invention discloses a synthesis method of a nitrogen-containing functional mesoporous polymer. The synthesis method is characterized by comprising carrying out demethylation on an intermediate prepared from 3-chloromethylanisole and a nitrogen heterocyclic compound, synthesizing a nitrogen-containing functional precursor from the demethylated intermediate, phenol and formaldehyde under alkaline conditions through a one-pot method, inducing self-assembling of the precursor through F127 as a template and ethanol solvent volatilization, and preparing a functional mesoporous polymer. The functional mesoporous polymer can be used as a catalyst in use of potassium iodide and is used for preparation of propylene carbonate through a cycloaddition reaction of carbon dioxide and epoxy propane. Compared with prior art, the synthesis method is simple and controllable, has a short synthesis period and has good repeatability. The nitrogen-containing functional mesoporous polymer has a high active site, an ordered mesoporous structure, a high specific surface area and a high pore volume and has good activity in a catalytic reaction of carbon dioxide and epoxy propane. The catalyst is easy to separate and can be recovered and recycled and is a novel environmentally friendly heterogeneous catalyst.

Description

technical field

[0001] The invention relates to the technical field of ordered mesoporous polymers, in particular to the synthesis and application of a nitrogen-containing functionalized mesoporous polymer that can be recycled to catalyze the cycloaddition reaction of carbon dioxide and propylene oxide. Background technique

[0002] The upper nitrogen atoms of nitrogen-containing heterocyclic compounds usually have unshared electron pairs to increase the density on the ring, which can undergo nucleophilic reactions. In the application of catalytic reactions, nitrogen-containing heterocyclic rings can catalyze the cycloaddition of carbon dioxide and propylene oxide reaction (Catalysis Communications 2015, 59, 201-205.), this reaction has 100% atom economy, and can effectively realize carbon dioxide emission reduction and resource utilization. However, homogeneous nitrogen-containing heterocyclic catalysts have problems such as separation and recovery difficulties during catal...
