    • Disclosed is a process for continuously reacting liquid alkylene oxide with a liquid substance comprising an organic compound with active hydrogen atoms and a catalyst in a reactor, wherein (1) the alkylene oxide is split before entering the reaction space into a first and a second part and, optionally, further parts, (2) said first part of alkylene oxide enters the reaction space of said reactor at a first location, (3) the liquid organic substance is supplied to the interior of said reactor at a second location downstream of said first location, (4) the liquid alkylene oxide enters the reactor at said first location over the entire-cross sectional area of the reaction space or gap at said location, (5) said second and, optionally, further parts of alkylene oxide are split off at said first location and are channeled from said first location to a third location and, when further parts of alkylene oxide are split off, to further locations in the reaction space or gap, through a separate tube for each part of alkylene oxide which is inserted into the reaction space, extends from said first location to said third or said further location of the reactor space, respectively, (6) said third location and optional further locations are located downstream of said second location and have a distance from said second location and from each other in flow direction of the reactor charge, and (7) said second and optional further parts of liquid alkylene oxide enter the reaction space at said third location and said optional further locations and are intermingled with the liquid reaction mixture and react with it on its way downstream towards the end of the reactor and preferred apparatuses for carrying out said process.
