| titleOfInvention | Process for the preparation of alkylene glycols |
| abstract | The present invention provides methods and reactors for preparing alkylene glycols from alkylene oxides. The alkylene oxide, water, homogeneous carboxylation catalyst and homogeneous hydrolysis catalyst are fed to a reactor comprising a carboxylation zone and a hydrolysis zone. One or more ejectors are used to mix carbon dioxide and liquid reagent in the carboxylation zone so that the alkylene oxide reacts with carbon dioxide in the presence of water in the carboxylation zone to produce alkylene. A reaction solution is formed comprising carbonate, water, homogeneous carboxylation catalyst and homogeneous hydrolysis catalyst. The reaction solution is supplied from the carboxylation zone to the hydrolysis zone, where the alkylene carbonate and water react to produce a product containing alkylene glycol, homogeneous carboxylation catalyst and homogeneous hydrolysis catalyst. Form a solution. Carbon dioxide released by the reaction of alkylene carbonate and water in the hydrolysis zone is supplied to the carboxylation zone. The product solution is recovered from the hydrolysis zone. |
