Title:
COMPOSITE ABSORBENT AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/036238
Kind Code:
A1
Abstract:
Disclosed are a composite absorbent and a method for using same in the absorption and conversion of ethylene oxide for the coupling co-production of ethylene carbonate. The composite absorbent comprises an ionic liquid and ethylene carbonate, wherein the ionic liquid is an imidazole ionic liquid, a quaternary ammonium ionic liquid and a quaternary phosphonium ionic liquid. The composite absorbent is used for absorbing ethylene oxide and carbon dioxide, and is also used in the absorption and conversion of ethylene oxide for the coupling co-production of ethylene carbonate.
