Title: Improvements in the production of branched chain alkanes
IPC: C07C5/27
Filed: 1940-10-02
Abstract: 556,894. Branched chain alkanes. ANGLOIRANIAN OIL CO., Ltd., and FAWCETT, E. W. M. Oct. 2, 1940, No. 14798. Drawings to Specification. [Class 2 (iii)] Normal alkanes are converted into branched chain alkanes by being contacted in the form of vapour together with a vaporized aluminium halide catalyst namely aluminium chloride or aluminium bromide, with porous or sorptive substances or surfaces at a reaction temperature not exceeding 250‹C. With alkanes having a number of carbon atoms higher than 4 the reaction products will depend on the reaction temperature. In general with the lower temperature ranges the parent alkane will yield the corresponding isoalkane, thus at temperatures below 75‹C. pentane will yield isopentane, but at the higher temperature ranges, e.g. 100‹-150‹C., a degradation takes place and the product consists largely of isobutane. The catalyst concentration is in general small and does not exceed 20 per cent. by weight of the hydrocarbon stream. It is preferred that a hydrogen halide activator should be present generally in amounts of 0.1 per cent. to 1.0 per cent. by weight. The reaction pressure varies from atmospheric to 50 atmospheres. It is an essential condition of the invention that the concentration of aluminium halide vapour does not exceed a concentration equivalent to the saturation pressure at the reaction temperature, so that no deposition of solid aluminium halide takes place. A diagrammatic representation of an apparatus is furnished. Examples are given of the treatment of n-butane according to the invention under varying conditions of temperature, pressure, catalyst and throughput.
