    Abstract: The invention relates to a catalyst molded body for preparing maleic anhydride by gas-phase oxidation of a hydrocarbon having at least four carbon atoms using a catalytically active composition containing vanadium, phosphorus and oxygen. The shaped catalyst body has an essentially cylindrical body having a longitudinal axis. The cylindrical body has at least two parallel internal holes which are essentially parallel to the cylinder axis of the body and go right through the body. The catalyst molded body has a large outer surface area, a lower pressure loss and sufficient mechanical stability.

    Abstract: A formulation is claimed, which contains at least one protective substance that is active with respect to cellulose-containing materials, such as wood-containing building materials in the form of solid wood or wood-based materials, and at least one specific compound with dispersing properties. The dispersants are branched comb-shaped polymers with polyether side chains, naphthalene-sulfonate-formaldehyde condensation products, melamine-sulfonate-formaldehyde condensation products and phosphatized polycondensation products. The formulations according to the invention are suitable in particular as plant protection agents and wood preservatives and are preferably used in the form of suspensions for pressure treatment of the respective building materials.
