Normal butane is isomerized to isobutane by means of a catalyst composition consisting essentially of 95 to 99 weight percent fluorosulfuric acid and 1 to 5 weight percent of a protic co-acid selected from the group consisting of hydrogen fluoride, sulfuric acid, trifluoromethanesulfonic acid and mixtures thereof. The isomerization is carried out under low temperatures and at short contact times.
