Abstract
A process for the alkylation of a C3-C10 isoparaffin with a C2-C10 olefin performed in the liquid phase in the presence of an acid catalyst where the reaction medium contains additional limited quantities of a solvent which is liquid under the alkylation conditions selected from aliphatic chlorohydrocarbons, dimethyl formamide, dimethyl acetamide, dimethyl sulphoxide, sulpholane, acetonitrile, or carbon dioxide dissolved in the said medium is described. The addition of these compounds improves the activity of the catalyst, making it possible to use smaller quantities of catalyst in comparison with known processes and also improves the selectivity for useful reaction products.
