The influence of added isobutane on the formation of unsaturated carbenium ions (considered to be precursors of carbonaceous deposits) from 1-butene was studied. The unequivocal results obtained by IR and UV-VIS spectroscopy show that the formation of alkenyl ions is strongly suppressed in the presence of isobutane. The role of isobutane is explained by its enhanced hydride ion donor character.
