Abstract

A catalytic material for the partial oxidation of organic compounds consists of boric or phosphoric acid or their salts. The materials are preferably mounted on a carrier; thus, clay, firebrick or magnesia is soaked with boric or phosphoric acid, or silica, kieselguhr, or a metallic oxide, carbonate or nitrate is introduced into molten boric acid. Mixed catalysts, obtained by adding boric or phosphoric acid to molten metal salts such as nitrates, may be used.ALSO:The partial oxidation of organic compounds is effected by passing the compound in the gaseous or vapour phase, in admixture with an oxygen-containing gas, over boric or phosphoric acid or their salts. The catalytic materials are preferably mounted on a carrier; thus clay, firebrick or magnesia is soaked with boric or phosphoric acid, or silica, Kieselguhr, a metallic oxide, carbonate or nitrate is introduced into molten boric acid. Mixed catalysts obtained by adding boric or phosphoric acid to molten metal salts such as nitrates, may be used. According to the examples, (1) formaldehyde is produced by passing ethylene and oxygen over boric or phosphoric acid or their salts mounted on burnt clay or diatomaceous earth; the gases may circulate over the contact mass, the formaldehyde being absorbed in water and further ethylene and oxygen being introduced continuously or at intervals; methane, acetone, ethyl alcohol and cyclohexanone may also be oxidized to formaldehyde in a similar way; (2) anthracene and air passed over the catalytic material yield anthraquinone, benzyl alcohol gives benzaldehyde and ethyl alcohol produces acetaldehyde.
