Title:
USE OF CATALYST CONTAINING SPIRO COMPOUND IN CATALYZING REACTION OF EPOXY COMPOUND AND CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2024/082333
Kind Code:
A1
Abstract:
Provided is the use of a catalyst in the catalysis of a reaction of an epoxy compound and carbon dioxide. The catalyst comprises a spirocyclic compound, and the spirocyclic compound comprises at least one of compounds as shown in the structural formula 1, wherein X is selected from a nitrogen element and a phosphorus element; Y is selected from halogen elements; and A and B are independently selected from any one of structural formulae a-d. Compared with a traditional non-spiro structure catalyst or a Lewis acid metal catalyst, the catalyst containing the spirocyclic compound as represented in structural formula 1 has the advantages of better catalytic effect, more stable performance and a longer service life when being used for catalyzing the reaction of an epoxy compound and carbon dioxide, and has both high efficiency and safety and wide use prospects.
