| titleOfInvention | Alkylation process |
| abstract | Alkyl aromatic hydrocarbons, particularly detergent alkylates, are prepared by reacting an aromatic hydrocarbon with a halogenated n-alkane in the presence of a Friedel-Craft catalyst in which the reaction is initiated at -25 DEG to 10 DEG C. and thereafter raising the temperature to within the range 30-100 DEG C. whereby aryl n-alkanes are formed having a relatively high proportion of mid-chain isomers. The first stage temperature is maintained for 5-60 minutes or until the reaction rate has fallen to 10% of the initial rate or until 75-95% of the alkyl halides have been converted. The mixture should be less than 50% solid and a solvent may be added, e.g. n-kerosene, carbon disulphide, pentane or liquid sulphur dioxide. The mixture is then rapidly heated to the higher temperature which is maintained for 4-40 minutes. |
