<p>Disclosed is a process for carrying out a cyclisation reaction, a polymerization reaction, an enzymatic reaction show - ing substrate inhibition, an enzymatic reaction showing product inhibition, a reaction showing precipitation of the substrate or of a reactant, the process comprising the steps of · a) diluting a fresh substrate (X) with solvent (S) to form a diluted substrate- solvent o mixture, and supplying this mixture to a reactor (2), · b) causing the reaction medium in the reactor to react, · c) discharging reaction mixture comprising reaction product, solvent, and substrate that has not reacted, to a first filtration membrane (6) which is permeable o to the solvent and impermeable to the substrate and to the catalyst or at least one of the reactants, · d) returning solvent from the per - meate side ( 11) of the first membrane to dilute the fresh substrate, and · e) returning retentate (10) comprising substrate which has not reacted, from the first filtration membrane to the reactor.</p> |
