发明名称 Method and device for the production of alkylene oxide addition products
摘要 A method for the production of alkylene oxide addition products comprising (i) charging a stirred reactor with a starting compound capable of adding on or inserting alkylene oxides, introducing at least one alkylene oxide plus a different diluent gas, wherein a portion of said alkylene oxide reacts in a liquid phase with said starting compound, and the remaining alkylene oxide together with said diluent gas forms a gas phase above the liquid phase, (ii) continuously drawing off said liquid phase from the bottom of the reactor via an outlet stub, and recycling to the top of the reactor via an external circulation system, which comprises at least one heat exchanger and at least one Venturi nozzle within said external circulation system, and (iii) metering said gas phase comprising alkylene oxide into said Venturi nozzle via a vacuum line.
