The present invention relates to a process for preparing 3-methyl-2-butenol (prenol) and 3-methyl-2-butenal (prenal) from 3-methyl-3-butenol (isoprenol), in which 3-methyl-3-butenol is subjected to a catalytic isomerization over a carbon-supported Pd catalyst in the presence of a gas mixture comprising 1% to 15% by volume of oxygen to obtain a first product mixture, and the first product mixture is subjected to an oxidative dehydrogenation over a Pd catalyst comprising SiOand/or AlOas support material, or over a carbon-supported Pd/Au catalyst in the presence of a gas mixture comprising 5% to 25% by volume of oxygen.

Process for producing prenol and prenal from isoprenol

The invention relates to a method for producing 2,3,5-trimethyl benzoquinone or a compound containing 2,3,5-trimethyl benzoquinone, the method comprising the following steps: Oxidation of 2,3,6-trimethylphenol with oxygen or an oxygen-containing gas in a two-or multi-phase reaction medium in the presence of a catalyst or catalyst system containing at least one copper (II)-halide to a mixture containing 2,3,5-trimethyl benzoquinone, characterized in that the reaction medium contains water and at least one secondary aliphatic acyclic alcohol having 6 or more, preferably 7 or more, carbon atoms.
