The invention relates to a process for oxidizing at least one organic substance with oxygen, which comprises the following steps: The invention further relates to an apparatus for performing the process.

Process and apparatus for oxidizing organic compounds

A method is provided for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent with a boiling point ranging from &#x2212;50&#xb0; C. (223 K) to 200&#xb0; C. (473 K) under atmospheric pressure, wherein the concentration of 3-chloropropyne in the liquid phase and in the gas phase is kept below the concentrations capable of deflagration by means of the type and amount of the diluent, the temperature and the total system pressure, together with the use of a 3-chloropropyne prepared, stored or transported in this way in the synthesis of dyestuffs, pharmaceutical and agricultural active ingredients, electroplating auxiliaries, disinfectants, steroids and growth hormones.

In an industrial process for the heterogeneously catalyzed gas-phase oxidation of propane with molecular oxygen to give acrolein, the feed gas mixture having an initial undiluted molar ratio of the reactants propane:O,of 7:3 is diluted with the reactant propane and, if desired, inert gases in such a way that the feed gas mixture comprises more than 70% by volume of propane and at least 5% by volume of O,.

A process for vinylation of an organic acidic-hydrogen compound, which entails reacting an organic acidic-hydrogen compound with acetylene or an acetylene-containing gas under elevated pressure and at elevated temperature in the presence of a base, wherein reactor regions initiating decomposition of acetylene are treated with an effective amount of a chemically inert oil of medium viscosity.
