This invention relates to a process for isomerizing paraffins comprising the step of contacting a feed containing paraffins with a catalyst comprising a synthetic porous crystalline material, designated MCM-68, which exhibits a distinctive X-ray diffraction pattern and has a unique crystal structure which contains at least one channel system, in which each channel is defined by a 12-membered ring of tetrahedrally coordinated atoms, and at least two further, independent channel systems, in each of which each channel is defined by a 10-membered ring of tetrahedrally coordinated atoms, wherein the number of unique 10-membered ring channels is twice the number of 12-membered ring channels.
