Abstract

The invention relates to a method for producing monoalkylene glycol, the method comprising: a) flowing a feed stream comprising alkylene oxide and water into a first reactor unit; b) subjecting the feed stream, in the first reactor unit, to first reaction conditions to obtain a first effluent comprising monoalkylene glycol, unreacted alkylene oxide and unreacted water, wherein the first reaction conditions in the first reactor unit are non-catalytic reaction conditions; c) flowing at least a portion of the first effluent to a second reactor unit; and d) subjecting said portion of the first effluent, in the second reactor unit, to second reaction conditions to obtain a second effluent comprising monoalkylene glycol, wherein the second reactor unit comprises a reactor comprising a catalyst bed and the second reaction conditions in the second reactor unit are catalytic reaction conditions.
