Abstract:
1. A process for preparing alkylene oxide addition products, comprising (a) providing a reactor with high internal surface area that is a micro tube bundle reactor consisting of a bundle of 10 to 100 individual capillaries with a length of 5 to 1000 cm and a diameter of 0.25 to 15 mm, (b) introducing alkylene oxide and compounds having a nucleophilic center into said reactor, and (c) reacting said alkylene oxide and said nucleophilic compounds in said reactor to form alkylene oxide addition products, wherein said alkylene oxide and said nucleophilic compounds are fed by means of a mixing and metering apparatus in which gaseous or liquefied alkylene oxide is dissolved in a liquid feed stream, such that the alkoxylation reaction takes place exclusively in the liquid phase.
