| titleOfInvention | Method for producing alkylene carbonate |
| abstract | In the present invention, when alkylene oxide is reacted with carbon dioxide in the presence of a phosphonium catalyst to produce alkylene carbonate, (a) alkylene oxide, carbon dioxide and phosphonium catalyst are continuously introduced into the reaction zone, Withdrawing the product stream containing alkylene carbonate and phosphonium catalyst from the zone; (b) separating the alkylene carbonate and phosphonium catalyst-containing stream from the product stream; (c) using the alkylene carbonate separated in step (b) as the product And (d) a method of recycling the phosphonium catalyst-containing stream separated in step (b) to the reaction zone, wherein the treatment of the alkylene carbonate and / or the catalyst with a carbon-containing sorbent is carried out. . |
