Abstract
The influence of added isobutane on the formation of unsaturated carbe nium ions (considered to be precursors of carbonaceous deposits) from 1-butene was studied. The unequivocal results obtained by IR and UV-VI S spectroscopy show that the formation of alkenyl ions is strongly sup pressed in the presence of isobutane. The role of isobutane is explain ed by its enhanced hydride ion donor character.
