Patent ID: 7312364

Claim:
A process for performing two chemically successive reactions in a loop reactor, comprising (reaction I) an optionally catalyzed equilibrium reaction of at least two high-boiling liquid reactants, in which essentially one high boiler is formed as an intermediate and at least one low boiler as a by-product, and (reaction II) a substantially diffusion-controlled reaction in which the liquid intermediate is reacted with at least one gaseous reactant to give the end product, wherein reactions (I) and (II), optionally after a start phase, are allowed to proceed simultaneously in the same loop reactor, and the loop reactor has a connectable gas-liquid circulation system coupled via an ejector mixing nozzle, in which circulated liquid phase is mixed in the ejector mixing nozzle with newly supplied gaseous reactant of reaction (II) ( 6 ) and/or gaseous reactant of reaction (II) aspirated by means of the ejector from the reactor via a connectable condenser ( 5 ), and fed to the reactor by a liquid jet ejector ( 2 ) for the reaction, the low-boiling by-product(s) of reaction (I) and also any low-boiling solvent being condensed and discharged in the condenser continuously over the duration of the process.
