Abstract

The invention provides an organic porous copolymer heterogeneous catalyst containing a quaternary phosphonium salt-phosphorus ligand. An organic porous copolymer containing the quaternary phosphoniumsalt-phosphorus ligand is obtained through copolymerizing an alkylene group-containing organic phosphine ligand and an alkylene group-containing quaternary phosphonium salt, a Lewis acid metal salt isadded or is not added to the obtained copolymer, and metal ions in the metal salt and bare phosphine in the organic porous copolymer containing the quaternary phosphonium salt-phosphorus ligand formcoordination bonds during the addition of the Lewis acid metal salt in order to obtain the organic porous copolymer heterogeneous catalyst containing the quaternary phosphonium salt-phosphorus ligand.The heterogeneous catalyst fully integrates the respective advantages of the quaternary phosphonium salt (used as a ring-opening nucleophilic reagent) and a phosphine-metal coordination compound (activated epoxy compounds) when applied to a coupling reaction technology of an epoxy compounds and carbon dioxide, and the proportion of the copolymerization monomer and the metal load are regulated tomake the obtained catalyst have extremely high activity and high stability.

Description

technical field

[0001] The field of the invention belongs to the field of heterogeneous catalysis, and specifically relates to a heterogeneous catalyst containing a quaternary phosphonium salt-phosphorus ligand organic porous copolymer and its preparation and application, and is specifically applied in the coupling reaction of carbon dioxide and epoxy compounds. Background technique

[0002] The design and synthesis of porous organic polymer materials has gradually become one of the new hotspots in the field of porous materials research. Compared with traditional inorganic microporous materials and metal-organic frameworks (MOFs), the framework of organic microporous polymers is composed of pure organic molecules, which are connected to each other by covalent bonds, and have open channels and excellent pore properties. . More importantly, due to the diversity of organic chemical synthesis methods, it provides a wealth of synthetic routes and construction methods for the con...
