Liquid-Phase Oligomerization of 1-Hexene Catalyzed by Macroporous Ion-Exchange Resins

Oligomerization of pure 1-hexene catalyzed by macroporous ion-exchange resins was performed in batch experiments at 350-390 K and 2 MPa. At 373 K, after 6 h, 1-hexene conversion was practically complete and the selectivity to dimers was 56%, that to trimers 0.8 and 43.2% to double-bond isomerization. By assuming an homogeneous kinetic model for olefin dimerization of second order reaction, a value of 64-68 kJ mol(-1) for apparent activation energy was obtained.
