Title: Treatment of hydrocarbons with activated phosphorous pentoxide
IPC: C07C4/06
Filed: 1936-05-14
Abstract: Processes in which hydrocarbons are reacted with other hydrocarbons or are subjected to thermal decomposition or polymerization are effected in the presence of phosphorus pentoxide and an activator comprising one of the following hydrides, viz., hydrogen sulphide, hydrogen chloride, hydrogen bromide, hydrogen iodide, hydrogen fluoride, or hydrogen cyanide. The proportion of hydride must not exceed one per cent, calculated on the hydrocarbons.  In place of the specified hydrides, substances which yield them under the reaction conditions may be used, e.g. a mercaptan, an alkyl chloride, or a nitrile.  The invention may be applied in processes for alkylating aromatic hydrocarbons by reaction with olefines, and examples are given of the reaction of benzene with ethylene at 250 DEG  C. and 30 atm. pressure in the presence of phosphorus pentoxide, lamp-black, and hydrogen chloride and sulphide.  At temperatures above those used for alkylation, generally at 350--550 DEG  C., the activated phosphorus pentoxide acts as a dealkylation catalyst; thus, diethylbenzene is converted into benzene and ethylene, and isooctane is converted into a mixture of gaseous olefines. Specifications 320,846, [Class 2 (iii)], 437,072, and 467,932 are referred to.  The Provisional Specification states that a small proportion of hydrogen may be added, in place of a hydride as specified above.ALSO:Processes in which hydrocarbons are subjected to thermal decomposition are effected in the presence of phosphorus pentoxide and an activator comprising one of the following hydrides, viz., hydrogen sulphide, hydrogen chloride, or hydrogen cyanide.
