    Abstract: 1,126,617. Unsaturated aldehydes and nitriles. STANDARD OIL CO. 14 Oct., 1965 [4 Nov., 1964], No. 43643/65. Heading C2C. A process for the production of olefinically unsaturated nitriles and/or olefinically unsaturated aldehydes comprises introducing molecular oxygen into the bottom zone of a reaction enclosure comprising at least two communicating reaction zones at different levels each containing a fluidized solids catalyst capable of catalysing the reaction of olefines with molecular oxygen and optionally ammonia, the zones being separated by at least one foraminous member with at least some openings large enough to allow catalyst passage therethrough and the amount of open area in the foraminous members being at least 7.5 to 50% of the total internal cross-sectional area; introducing into a reaction zone other than that into which the molecular oxygen was introduced : (a) propylene or isobutylene, and, if the product is intended to be a nitrile, (b) ammonia; maintaining an elevated temperature throughout the reaction zones; passing the reactant vapours upwards through the communicating zones containing the fluidized catalyst; and recovering the product produced, the volume of the reaction enclosure upstream of the reaction zone receiving the component (a) and the optional component (b) being from 5 to 75% of the total volume of the enclosure. The catalyst is preferably composed of a mixture of antimony oxide and the oxide of at least one other polyvalent metal, such as uranium, iron, thorium, cerium and manganese. The production of acrylonitrile, methacrylonitrile, acrolein and methacrolein is described.

    Abstract: Diolefins or aromatic hydrocarbons are obtained from a C4-C8 mono-olefin free from quaternary carbon atoms by reaction with oxygen in contact with a fluidized solid oxide catalyst in a plurality of communicating reaction zones. Many catalysts are specified and are preferably arranged in superposed zones in a reactor separated by perforated plates. In one embodiment, the hydrocarbon is introduced into a zone above the bottom and oxygen introduced into the bottom zone to effect regeneration. The temperature may be 325-1000 DEG C., the pressure 0-300 p.s.i.g., contact time 0.1-50 seconds, oxygen to olefin mol. ratio 0.3-3 : 1 and water (if added) to olefin mol. ratio 0.1-6 : 1. Aromatics are generally obtained from cyclic olefins and diolefins from acyclic olefins. Specifications 902,952, 971,036 and 971,038 are referred to.
