    摘要: A catalyst is produced by bonding a homogeneous catalyst to the surface of a catalyst support. A catalyst may include a catalyst support, a spacer molecule bonded to the catalyst support, and a homogeneous catalyst bonded to the spacer molecule. A catalyzed reaction can be carried out by providing reactants in a first phase and providing a catalyst as described herein in the first phase.

    摘要: The invention relates to a composite membrane with a separation-active membrane layer and a supporting membrane, a process for the production of the same, and a process for using the same. The composite membrane according to the invention is distinguished by the fact that the separation-active membrane layer comprises a polymer hardened by electromagnetic radiation with a wavelength that is less than 800 nm and/or by electron beams. The process according to the invention is distinguished by the fact that a layer of a solution of a polymer that can be hardened by electromagnetic radiation with a wavelength that is less than 800 nm and/or by electron beams and an initiator substance is applied to a supporting membrane and subsequently is hardened by electromagnetic radiation and/or by electron beams. The use according to the invention serves to retain low-molecular substances from organic solutions.

    摘要: The invention relates to a membrane for the separation of material mixtures by the principle of vapor permeation or pervaporation, in particular for the dewatering of organic solvents, comprising at least one support layer and at least one material-selective separation layer located thereon, and a method for production of such a membrane. The material-selective separating layer is made from polyvinyl alcohol, containing at least one metallic element and/or a derivative thereof. The method includes the addition of polyvinyl alcohol to a solvent, adding an organometallic compound to the solvent/polyvinyl alcohol mixture, and then applying the solvent/polyvinyl alcohol/organometallic compound mixture to the support layer as the material-selective separating layer.
