Abstract

A bubble column reactor is described which is characterized by a slenderness ratio at a ratio of height to diameter of 2 to 50, a feed, at the bottom end of the bubble column, for the ethylene glycol carbonate (EGC) or propylene glycol carbonate (PGC) already present serving as reaction medium, one or more metering sites for the starting materials CO2 and ethylene oxide (EOX) or propylene oxide (POX) above the feed for the reaction medium, an outlet for the reaction mixture at the top end of the bubble column, a dividing apparatus connected thereto for the reaction mixture flowing off for dividing it into reaction mixture to be taken off and worked up on the one hand and reaction mixture to be recycled on the other hand and additionally a return line to the feed for the reaction mixture to be recycled. This bubble column reactor can be advantageously used in a process for the continuous preparation of EGC or PGC which is carried out in the temperature range from 100 to 200°C, in the pressure range from 5 to 200 bar and at a molar ratio of 1.01 to 1.5 mol of CO2 per mol of alkylene oxide in EGC or PGC
already present as reaction medium in an amount which is 7 to 350 times that of the newly formed EGC or PGC.
