Abstract: Olefinically unsaturated hydrocarbons are prepared from corresponding paraffinic hydrocarbons, in particular propylene is prepared from propane, by dehydrogenation over a catalyst comprising an oxide of a transition metal of group IV B of the Periodic Table, eg. TiO 2 or ZrO 2 , and possibly at least one element selected from among elements of transition group VIII, eg. palladium, platinum or rhodium, and/or an element of transition group VI, eg. chromium, molybdenum or tungsten, and/or rhenium and/or tin and possibly a compound of an alkali metal or alkaline earth metal, a compound of main group III or transition group III or zinc.

Abstract: Enol ethers of the formula Iwhere R1 is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical which may carry further substituents which do not react with acetylenes or allenes, and the radicals R, independently of one another, are hydrogen or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which may be bonded to one another to form a ring, and m is 0 or 1, are prepared by reacting an acetal or ketal of the formula IIwith an acetylene or allene of the formula III or IVwhere R and R1 have the abovementioned meanings, in the gas phase at elevated temperatures in the presence of a zinc- or cadmium- and silicon- and oxygen-containing heterogeneous catalyst.

Abstract: The invention relates to a method for combinatorially producing a library of materials by means of an electrochemical deposition in an array. The inventive library is made from an array of containers that consist of an electroconductive material, are open to the top and are electroconductively connected to a shared current supply device and is made from a corresponding array of auxiliary electrodes that are electroconductively connected to a shared current supply device and are arranged in such a way that an auxiliary electrode plunges into a container respectively or can be introduced therein without touching said container. The inventive method comprises the following steps: filling the containers with electrolytes having different compositions and containing electrolytically separable elements and applying an electric voltage between the current supply devices of the containers and auxiliary electrodes for obtaining an electrolytic deposition on the surfaces of the containers.
