Embodiment 1

[0012] Example 1: The cycloaddition reaction of carbon dioxide and epoxide was carried out in a 25 mL stainless steel autoclave equipped with a magnetic stirrer. First, put 50mg of Cu-BTC catalyst and 20mmol of epoxide in the autoclave, add 20mg of co-catalyst (tetrabutylammonium bromide), feed a certain amount of carbon dioxide, and react at a temperature of 110°C and a pressure of 10bar for 6h.

Embodiment 2

[0013] Example 2: The cycloaddition reaction of carbon dioxide and epoxide was carried out in a 25 mL stainless steel autoclave equipped with a magnetic stirrer. First, 50 mg of Co-BTC catalyst and 20 mmol of epoxide were placed in a high-pressure reactor, 20 mg of cocatalyst (tetrabutylammonium bromide) was added, a certain amount of carbon dioxide was introduced, and the reaction was carried out at a temperature of 110 °C and a pressure of 10 bar for 6 h.

Embodiment 3

[0014] Example 3: The cycloaddition reaction of carbon dioxide and epoxide was carried out in a 25 mL stainless steel autoclave equipped with a magnetic stirrer. First, put 50mg of Ni-BTC catalyst and 20mmol of epoxide in a high-pressure reactor, add 20mg of co-catalyst (tetrabutylammonium bromide), feed a certain amount of carbon dioxide, and react at a temperature of 110°C and a pressure of 10bar for 6h.

Abstract

The invention relates to a catalyst M-BTC which is synthesized by using M<2+> (one or more of Cu, Co, Ni, and Zn) as a central ion and trimesic acid (BTC) as a ligand according to a hydrothermal method and has an efficient catalytic effect on the cycloaddition reaction of carbon dioxide and epoxide. A preparation method and an evaluation method of the catalyst are as follows respectively: by a hydrothermal synthesis method, the M-BTC catalyst is synthesized through the coordination of the M<2+> and the BTC at a certain temperature and within a certain period of time; the catalyst has good performance in catalyzing the cycloaddition reaction of the carbon dioxide and the epoxide under the conditions that the temperature is 80-140 DEG C, the pressure is 5-15 bars, the time is 2-14 hours and the catalyst amount is 20-80mg.

Description

technical field [0001] The present invention uses M 2+ (One or more of Cu, Co, Ni, Zn) as the central ion, trimesic acid as the ligand, synthesized by hydrothermal synthesis with high specific surface area and non-magnetic catalyst M-BTC, in different reactions It can be used in the cycloaddition reaction of carbon dioxide and epoxide under the conditions of high-efficiency catalysis. Background technique [0002] As a gas that can cause the greenhouse effect, carbon dioxide has caused great harm to the natural environment, but it is also a precious C1 resource, which has the characteristics of abundant yield, non-toxic, cheap, and non-flammable. In recent years, the chemical fixation of CO 2 More and more attention has been drawn to the use of CO 2 This kind of non-toxic and non-flammable raw material can obtain high value-added products, which meet the requirements of green chemistry and have great environmental and economic effects. Using CO 2 The reaction with epoxid...
