Abstract: A process for the continuous catalytic conversion of organic compounds, that, together with unwanted attendant materials, form a starting substance: first the organic compounds of the starting material are purposely extracted by means of condensed fluids. Then the extract, containing the condensed fluids and organic compounds as the reaction mixture is contacted with a catalyst for the catalytic conversion of the organic compounds to form a product mixture, which contains the individual products of the catalytic conversion. The product mixture is separated from the reaction mixture and the fluids employed are, optionally, conducted back for extraction.
