A process for a continuous production of a polyetherol first involves reacting a catalyst () with an alcohol starter () or an alkoxylated precursor, to give a mixture comprising an alcoholate and water. Water is then removed from the mixture. The process further involves feeding the alcoholate into a bubble column and feeding an alkylene oxide into the bottom of a compartment of the bubble column, such that the alkylene oxide rises in the alcoholate. The alkylene oxide then reacts with the alcoholate or a secondary product from the reaction between the alcoholate and alkylene oxide, to give the polyetherol.
