METHOD OF PRODUCING ALKYLENE GLYCOL Russian patent published in 2013 - IPC C07C31/20 C07C29/12 C07C29/09 C07C69/96 C07C68/04 C07D317/36 C07D317/38 B01J19/24 

FIELD: chemistry.

SUBSTANCE: invention relates to a reactor for producing alkylene glycol, which is used as a starting substance in production of fibre, polyethylene terephthalate plastics and resins, and is also included in car antifreeze liquids from ethylene oxide, and a method of producing alkylene glycol using said reactor. The disclosed reactor has: (a) a carboxylation zone having one or more inlet openings for liquid reagents which contain alkylene oxide, water, a homogeneous carboxylation catalyst and a homogeneous hydrolysis catalyst, one or more inlet openings for carbon dioxide, one or more ejectors for mixing carbon dioxide with liquid reagents, and one or more outlet openings for the reaction solution which contains alkylene carbonate, water, the homogeneous carboxylation catalyst and the homogeneous hydrolysis catalyst; (b) a hydrolysis zone, having one or more inlet openings for the reaction solution, one or more outlet openings for carbon dioxide, and one or more outlet openings for the product solution which contains alkylene glycol, the homogeneous carboxylation catalyst and the homogeneous hydrolysis catalyst; and (c) a channel through which carbon dioxide can be fed from the hydrolysis zone into the carboxylation zone, where carboxylation zone and the hydrolysis zone are located in one reaction vessel, and where the carboxylation zone is separated from the hydrolysis zone by an inner partition.

EFFECT: objects enable to obtain the end product with high selectivity.
