A kind of preparation method of organic porous material

Abstract

The invention provides a preparation method of an organic porous material. The preparation method includes the following steps that ion-like liquid and 2,4,6-trihydroxy-1,3,5-benzene trioxin are addedinto a reaction vessel, then a catalyst is added to be subjected to ultrasonic processing and mixing evenly, the reaction vessel is placed in liquid nitrogen to be frozen for 1-3 min, vacuumized to 0.01-1 pa, and sealed, and a product is obtained through a reaction for 24-72 h at 90-150 DEG C; the ion-like liquid is prepared from a hydrogen bond donor and a hydrogen bond receptor, and the hydrogen bond donor is one of carbamide and thiourea; the catalyst is one of scandium trifluoromethanesulfonate, europium trifluoromethanesulfonate, indium trifluoromethanesulfonate, ytterbium trifluoromethanesulfonate hydrate, yttrium trifluoromethanesulfonate, and zinc trifluoromethanesulfonate; the product is washed through a solvent, and filtered after Soxhlet extraction for 12-48 h; and the productis dried under the vacuum condition to obtain the organic porous material. According to the preparation method of the organic porous material, use of volatile and toxic organic solvents can be avoided, and environmental-friendly performance is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical catalysis, and in particular relates to a preparation method of an organic porous material. Background technique [0002] The economic development and industrialization of human society largely depend on the combustion and utilization of non-renewable energy sources such as oil, coal and natural gas. A large amount of CO produced by combustion 2 Serious impacts on the greenhouse effect and global climate change, such as an increase in the frequency of extreme weather events, a significant reduction in polar glaciers, and a decline in the number of species. CO 2 Adsorption and storage is the current reduction in atmospheric CO 2 One of the more effective solutions to content is the focus of research in recent years. [0003] Currently used to adsorb CO 2 The most common methods are solution absorption, solid material adsorption and membrane technology. The absorption of the solution is limit...
