摘要:
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.

摘要:
The invention relates to mixed oxide catalysts made of hollow shapes for the catalytic gas phase oxidation of olefins, and to a method for producing the catalysts by applying them as a layer to a carrier made of organic material and removing said organic material. The reaction into aldehydes and carboxylic acids occurs by air or oxygen in the presence of inert gases in different quantity ratios, at elevated temperatures and pressure in the presence of said catalysts.
