Embodiment Construction

[0032] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0033] 1. Synthesis of zinc porphyrin functionalized with imidazolium ionic liquid

[0034] Its molecular structure of the imidazolium ionic liquid functionalized zinc porphyrin provided by the invention is as follows:

[0035]

[0036] The ZnPp-4EtIm + Br - The synthesis of is divided into two steps:

[0037] 1. Synthesis of H 2 Pp-4EtIm + Br -

[0038] In a 250mL three-necked flask, 100mL DMF (solvent) was added, then 0.44g5,10,15,20-tetrakis(4-imidazolyl)phenylporphyrin and 6.0g ethyl p-toluenesulfonate were dissolved in DMF, and then Heat to 100°C and reflux for 72 hours. After the reaction, DMF is distilled off under reduced pressure. After cooling to room temperature, 40 mL of water is added, and then washed with chloroform for several times until the lower chloroform layer has no color. Remove the chloroform layer and ad...

Abstract

The invention discloses imidazole ionic liquid functionalized zinc porphyrin and an application thereof. The molecular structure of the imidazole ionic liquid functionalized zinc porphyrin is shown inthe specification, wherein the imidazole ionic liquid functionalized zinc porphyrin can be used for efficiently catalyzing the cycloaddition reaction of CO2 and epoxy compounds under the conditions of no solvent, no cocatalyst and mild conditions, wherein the catalytic performance is superior to most of catalysts reported at present.

Description

technical field [0001] The present invention relates to a kind of compound and application thereof, be specifically related to a kind of imidazolium ionic liquid functionalized zinc porphyrin and its CO 2 The application in the cycloaddition reaction with epoxy compounds belongs to the field of chemical technology. Background technique [0002] The use of renewable resources is an important prerequisite for sustainable development, CO 2 As a renewable carbon resource, it has attracted much attention in the field of organic synthesis. However due to CO 2 have high stability, so CO 2 The high-value utilization of energy often requires huge energy input. An effective method is CO 2 React with high-energy starting materials (such as hydrogen, olefins, and small molecule epoxy compounds) to produce high value-added chemical products. [0003] CO 2 Reaction with epoxides to form cyclic carbonates is a viable application. As an important chemical raw material, cyclocarbonate...
