It is shown, that with the usage of super acid complexes based on aluminum halides and polyhalogenmethanes at a temperature of 20°C and with the introduction of surface-active materials and cracking inhibitor into the reaction mixture, the effective process of n-pentane isomerization proceeds, the conversion of which reaches 95% and up to 90% under selectivity of isoparaffins formation. It is specified that with the increase of modal ratio of aluminum chloride in the catalyst system, the necessary amount of surface-active materials, which provide the growth of initial hydrocarbon conversion, goes down. It is shown, that as the inhibitor of cracking competitive reaction during the n-pentane isomerization can be used benzole, that leads to growth of izopenthane out – the base product.
