Abstract

Maleic acid or anhydride is made by oxidizing (1) an unsaturated hydrocarbon of 2 or 3 carbon atoms, or (2) a compound containing only carbon, hydrogen and oxygen and having 2 or 3 carbon atoms, in the vapour phase with an oxygen-containing gas in presence of an oxidation catalyst, and recovering the maleic acid. The temperature range may be 250-400 DEG C., and the amount of oxygen used should exceed that necessary to effect complete combustion. The mixture preferably consists of air containing 1-5 per cent of the organic compound. Catalysts specified are the oxides or salts of vanadium, bismuth, molybdenum, uranium, tungsten, chromium, and manganese, preferably the oxides of phosphorus or molybdenum. In examples, the following substances are oxidized with air using alumina or silica gel impregnated with phosphomolydic acid:-propylene, ethyl alcohol, ethylene, acetaldehyde, acetic acid, propyl alcohol, and acetone.
