Abstract
Isobutane/2-butene alkylation catalyzed by binary mixtures of acidic ionic liquids (ILs) and strong acids (sulfuric acid or H2SO4 and triflic acid or CF3SO3H) was investigated. The catalytic performances of H2SO4 and CF3SO3H were considerably improved when ILs were added. Using [Emim][OTf]-CuCl/H2SO4 as the catalyst, an alkylate with a high content of the desired trimethylpentane (up to 79.6 wt%) and a high research octane number (up to 99.1) was obtained. The results of electrospray ionization-mass spectrometry indicated that the better distributions of the products obtained with the IL/acid mixtures were due to the Cu-containing anions and cations of the ILs.
