    Publication number: 20180361319
    Abstract: The present invention relates to production processes for reactive monomer species. The method described herein may be used in a variety of reactive monomer production processes to optimise the use of polymerisation inhibitor compounds, which may lead to further advantages such as debottlenecking or elimination of process plant separation unit(s). The method provides for the separation of oligomeric/polymeric species, inhibitor compounds and reactive monomer, optionally in the presence of unreacted raw materials or solvent(s), within the production process by means of membrane filtration, particularly through the use of solvent stable membranes, and in particular by applying organic solvent nanofiltration membranes.

  • Separation off of a homogeneous catalyst from a reaction mixture with the help of organophilic nanofiltration
    Patent number: 10155200
    Abstract: The invention deals with the separation of homogeneous catalysts from reaction mixtures with the help of organophilic nanofiltration. It is based on the object of indicating an option as to how organophilic nanofiltration can be used economically for separating off homogeneous catalysts from reaction mixtures if the separation-active material of the membrane satisfying the separation aim is not available in sufficiently large amounts or only at high cost. This object is achieved by taking into consideration a particular membrane performance indicator during the design and/or the execution of the corresponding membrane separation process.
