摘要： A process for the preparation of carbonyl compounds by the oxydehydrogenation of (C.sub.1 -C.sub.4)-alcohols is carried out at a temperature from 400.degree. to 700.degree. C. in the presence of a silicate catalyst which has been doped with silver and silver ions. By means of the process carried out at relatively low temperatures, for example, are that high yields are achieved, the content of carbon monoxide is low and the product gas contains, apart from carbon dioxide, no further determinable by-products and has a low water/formaldehyde ratio.

摘要： A method for manufacturing coated short fibers, in which the short fibers are coated in a reactor with at least one coating agent. The method includes exposing a short fiber bundle having a coating or a plastic matrix to a high-frequency field which dissolves the coating or the plastic matrix. The fiber bundle is separated into individual fibers and are coated by chemical vapor deposition on all sides by at least one coating agent present in a gas phase. A combination of mechanical and microwave treatment is preferably provided to loosen the short fiber bundles.

摘要： The invention relates to the stabilization of the activity and/or the reactivation of molybdoheteropoly acid catalysts in vapor-phase oxidations, such as the oxidehydrogenation of isobutyric acid or its lower esters to methacrylic acid or its lower esters, by means of an oxidizing treatment of the catalyst in which compounds of catalyst constituents are added, at temperatures ranging from 200.degree. to 400.degree. C., with an oxygen-containing gas.The inventive activation measures can be carried out either during the catalytic vapor-phase reaction, such as oxihydrogenation in particular, or intermittently to alternate therewith, and optionally also physically separated in part from each other.
