Abstract
The invention relates to a method for producing alkylene oxide addition products. The method according to the invention is characterized by (a) contacting ethylene and/or propylene with an oxidizing agent in a first structured reactor (“μ reactor”) and (b) feeding the ethylene oxide and/or propylene oxide so obtained, optionally after purification, to a second structured reactor where it is reacted with a compound having a nucleophilic molecular group.
Claims35
A process for preparing alkylene oxide addition products, characterized in that
- (a) ethylene and/or propylene is contacted with an oxidizing agent in a first structured reactor (“μ-reactor”) and
- (b) the ethylene oxide and/or propylene oxide obtained, optionally after purification, is fed into a second structured reactor in which it is reacted with a compound having a nucleophilic molecular group.
