Abstract
A catalyst for hydrocarbon isomerization having the formula AlCl2SO2R where R is an aromatic hydrocarbon radicle, may be prepared by liquifying dry sulphur dioxide on to powdered aluminium chloride at a low temperature, allowing to warm up to room temperature to form a syrup, and treating with dry benzene at an elevated temperature at or below its boiling point to give a solid product.ALSO:Branched chain saturated aliphatic hydrocarbons are obtained from normal or less branched ones by treating at an elevated temperature not above 350 DEG C. with a catalyst having the formula AlCl2SO2R, where R is an aromatic hydrocarbon radicle. Such a catalyst may be prepared by liquefying dry sulphur dioxide on to powdered aluminium chloride at a low temperature, the mixture being allowed to warm up to room temperature to form a syrup which is treated with dry benzene at an elevated temperature at or below its boiling point, yielding a solid which may be used as pieces or granules or on a support. Isomerization may be effected in liquid or vapour phase at 50-200 DEG C., with promoters such as hydrogen chloride or water present if desired. In an example, n-butane is treated at 125 DEG C. and normal pressure.
