In a loop reactor, an alkylene oxide is reacted with an organic compound having a reactive hydrogen atom, where a gas circuit (5,7,4) and a liquid circuit (2,3,4) are arranged around the reactor (1) and coupled to each other via a jet intake mixing nozzle (4). Crucial for the completeness of the reaction and for the suppression of the formation of by-products, such as dioxane, is a reduction in the temperature of the entire alkylene oxide gas phase to a temperature of below that of the liquid phase, which is effected by feeding in, and evaporating, liquid alkylene oxide and cooling the gas phase at the walls of the equipment (13).
