Abstract
<PICT:0907148/III/1> Apparatus suitable for telomerization reactions (see Group IV(b)) comprises a vessel 4 (preferably tubular and vertical) with a means for controlling the temperature of the reactants by heat exchange through the walls thereof, e.g. the jacket 8 for a cooling liquid and a device for causing a telogen in liquid form (see Group IV(b)) to form a liquid film over the inside walls of the vessel, e.g. the rotary basket 11 on shaft 20, the liquid being preheated in heater 3. Gaseous olefine is fed under pressure through piping 7. Liquid products are discharged through 13, cooled in 14, and passed to separator 15 for recycle of gaseous olefine via 16 and to distiller 17 for recycle of telogen via 19. Reaction product is taken off at 18.ALSO:Telomers are prepared from gaseous olefines by a process in which the telogen, together with a polymerisation catalyst, is fed to the reaction chamber wherein the telomerisation is to take place under superatmospheric pressure, in the form of a liquid film running at the periphery of said chamber, in immediate contact with the walls, through which heat exchange takes place. Ethylene and propylene are specified as the olefine. The telogen may itself be liquid at room temperature to reaction temperature (such as carbon tetrachloride, chloroform, monochloroacetic acid, trichloroacetic acid, ethyl bromoacetate, mono- and diethyl malonate, methyl formate and methyl trichloroacetate), or may be dissolved in a suitable solvent (such as tribromoacetic acid and hexachloroethane in pentane, octane or hexadecane; and hexabromoethane, dibromoethane and dibromoacetophenone in dioxane). Suitable catalysts are acyl oxides such as benzoyl peroxide; azoisobutyronitrile; and metal halides.
