The catalytic isomerization of n-butane at 298/sup 0/-413/sup 0/K and n-pentane at 343/sup 0/-413/sup 0/K in a packed-bed flow reactor at 1 atm in the presence of aluminum chloride/sulfonic acid resin was accompanied by disproportionation and cracking. The selectivity to isomerization products was approx. 40% for n-pentane and > 99% for n-butane. Kinetics of n-butane isomerization at 308/sup 0/-338/sup 0/K were determined by using a partially deactivated catalyst batch, and the dependence of the isomerization rate on the partial pressure of n-butane was fitted using a power-law or a Langmuir-Hinshelwood rate equation. Alkylations of benzene with propylene catalyzed by sulfonic acid resin at 328/sup 0/K and aluminum chloride/sulfonic acid resin at 295/sup 0/K gave isopropylbenzene and mono- to tetra-isopropylbenzenes, respectively. A catalyst deactivation model was developed and used to correlate the time-dependent behavior of n-butane isomerization and benzene propylation. The data indicated that Broensted acid sites are responsible for the activity of the supported aluminum chloride catalyst.
