Abstract
Benzene or a mono-alkyl benzene of which the alkyl group contains between one and four carbon atoms is alkylated in the liquid phase by means of an alkene containing between 2 and 4 carbon atoms at a temperature above 160 DEG C. in the presence of a cracking catalyst having a water content below 3.5 per cent by weight and an L.H.S.V. of at least 3. A cracking catalyst is defined as a catalyst which may be used in the cracking of petroleum. This may be a silicate of one or more of the metals aluminium, magnesium, and zirconium, optionally in the presence of smaller quantities of the oxides of calcium, sodium, potassium, and of traces of hydrogen, carbon and sulphur. Preferred catalysts are those of the aluminium silicate type produced according to the method described in Specification 504,614, [Group III], containing 85-90 per cent of SiO2 and 15-10 per cent of Al2O3. The catalyst may be surface treated by heating at 600 DEG C. for 1-24 hours in steam, or at 800 DEG C. for 1-24 hours in hot air, or in aqueous HF solution at air temperature. The moisture content of the catalyst is preferably between 0.1 and 0.2 per cent by weight. In examples, cumene is alkylated with propene according to the invention to give paradi-iso propyl benzene which may be converted to terephthalic acid by the processes of Specifications 737,439, 749,186 and 749,187.
