| titleOfInvention | Process for the photo-chemical oxidation of organic and inorganic compounds |
| abstract | In the photochemical oxidation of organic or inorganic compounds by irradiation in the presence of oxygen and a catalyst of the anthraquinone type, an auxiliary catalyst is added to accelerate the reaction and prevent the formation of undesired bye-products. The auxiliary catalyst may be (1) an alkali such as soda, potash, or lime, (2) an adsorbent such as carbon, silica gel, fullers' earth, or clay, or (3) a metallic oxide or salt, particularly of copper, bismuth, iron, vanadium, or silver. Mixtures of auxiliary catalysts from more than one of the above groups may be used. According to examples (1) 30 litres of toluene receive an addition of 0,4 per cent of anthraquinone and 5 litres of lime water or 1,5 k.g. of granular carbon are added. The mixture on treatment with oxygen in presence of sunlight yields a very pure benzoic acid; (2) a solution of paraffin oil in benzene is oxidized to fatty acids using anthraquinone and caustic soda as catalysts; (3) lepidine is oxidized to 2-hydroxy-quinoline-4-carboxylic acid in presence of anthraquinone and 0,1 per cent of iron cinchonate; (4) chromic sulphate is precipitated by caustic soda and oxidized to chromic acid using granular carbon as auxiliary catalyst; (5) hydrogen sulphide or sulphur dioxide is oxidized to sulphuric acid using granular carbon; (6) benzene is chlorinated by oxidation in presence of hydrochloric acid, anthraquinone and ferric oxide.ALSO:In the photochemical oxidation of organic compounds by irradiation in the presence of oxygen and a catalyst of the anthraquinone type, an auxiliary catalyst is added to accelerate the reaction and prevent the formation of undesired bye-products.
