Abstract
The invention concerns the catalytic alkylation of at least one isoparaffin selected from the group formed by isobutane and isopentane in the presence of at least one olefin containing 3 to 6 carbon atoms per molecule, using a catalyst comprising 40% to 99% by weight of an acid selected from acids with formula R--SO.sub.3 H where R is fluorine or an alkyl group or a fluorinated alkyl group, R preferably being F or CF.sub.3, and more preferably CF.sub.3, and 1% to 60% by weight of a solvent selected from the group formed by sulpholane, dimethylsulphoxide and dioxanes, preferably sulpholane.
Claims13
A process for the catalytic alkylation of at least one isoparaffin selected from the group consisting of isobutane and isopentane comprising reacting said at least one isoparaffin with at least one olefin containing 3 to 6 carbon atoms per molecule in a reaction zone in the presence of a catalyst comprising 40% to 90% by weight of an acid of the formula R--SO.sub.3 H where R is fluorine or a fluorinated alkyl group, and 10% to 60% by weight of a dioxane solvent.
