摘要： A supported catalyst comprising a catalyst component carried on a support in the form of a rigid inorganic foam made of one or more layer minerals, a process forthe preparation of the catalyst by intoducing a catalyst component onto and/or into a pre-formed foam support or by incorporating a catalyst component in the foam support during production of the support and a process for carrying out a chemical reaction by contacting reactants in vapour or liquid form with the supported catalyst. The catalyst affords advantages in terms of one or more of low catalyst loading, reaction efficiency, yield and selectivity.

摘要： Polyaryletherketones are prepared by polymerisation of a halogen-containing aryl ketone in the presence of a stoichiometric excess of a base and a copper salt. The halogen-containing aryl ketone may be 4-chloro-4'-hydroxybenzophenone. A basic copper salt may be used but the base used to provide the excess of base is an alkali metal hydroxide, carbonate or bicarbonate.
