A catalytic composition comprises at least one Bronsted acid, dissolved in a non-aqueous liquid medium with an ionic nature. A catalytic composition comprises at least one Bronsted acid, dissolved in a non-aqueous liquid medium of formula (I) with an ionic nature. Q<+>A<-> Q<+> = organic cation; and A<-> = anion that is different from the Bronsted acid anion. Independent claims are included for: (1) An acid catalysis process which uses catalytic composition; (2) A method of alkylation of aromatic hydrocarbons by 2-20C olefin which involves using the catalytic composition; (3) Dimerization of isobutene which involves using catalytic composition, such that molar ratio of Bronsted acid to ionic liquid is 0.001/1-0.1/1; (4) Oligomerization of olefins which involves using catalytic composition, such that molar ratio of Bronsted acid to ionic liquid is 0.01/1-1/1; (5) Alkylation of at least one olefin with an isoparaffin to produce paraffinic hydrocarbons, by using catalytic composition, such that molar ratio of isoparaffin to olefin is 2/1-100/1. The isoparaffin is chosen from isobutane, methyl-2-butane, methyl-2-pentane or methyl-3-pentane. The olefin is ethylene, propylene, n-butene, isobutene, n-pentene or isopentene; (6) Isomerization of double bond of 4-30C olefin; and (7) Purification of olefin mixture. |
