Title:
SYNTHESIS METHOD FOR ALKYLENE CARBONATE
Document Type and Number:
WIPO Patent Application WO/2023/182772
Kind Code:
A1
Abstract:
The present invention relates to a synthesis method for alkylene carbonate, for example, alkylene carbonate comprising propylene carbonate, ethylene carbonate, and the like and, more specifically to, a synthesis method for alkylene carbonate comprising mixing a liquid compound of chemical formula 1 and hydrogen carbonate (MHCO3). According to the synthesis method of the present invention, use of carbon dioxide, ethylene oxide, propylene oxide, and the like is unnecessary, and alkylene carbonate may be obtained in high yield even under relatively low-temperature atmospheric pressure.
