Conclusions 1. The conversion of piperylene to isoamylenes in the presence of NiSO4-Al2O3 occurs in two stages: a) hydrogenation of the diene to n-olefins, and b) skeletal isomerization of the n-olefins. 2. The content of 2-pentenes in the fraction of n-pentenes at low influence by skeletal isomerization is appreciably greater than that at thermodynamic equilibrium, whereas for 1-pentene it is lower than the equilibrium value. The ratio of trans-2-pentene to the cis isomer is significantly greater than the equilibrium value. 3. In conditions of skeletal isomerization, the ratio of 2-methyl-2-butene yield to 2-methyl-1-butene exceeds the thermodynamic equilibrium value, consequently, 2-methyl-2-butene is the primary product of isomerization of n-pentenes.
