✦ Synopsis


The product of butene oligomerization in NaH-Y zeolites decomposes at high temperatures forming alkene molecules. They may desorb or undergo further transformations in the zeolitic supercages forming alkanes and polycyclic aromatic compounds. This last process occurs in several stages depending on the temperature. The rates of particular stages increase with the concentration and acid strength of the OH groups vibrating at 3640 cm -1. These OH groups were found to participate in the formation of polyenes.

Butene oligomerization on NaH-Y zeolites in which some OH groups vibrating at 3640 cm -1 were removed by pyridine adsorption was studied by the i.r. spectroscopy. In each zeolitic supercage in which butene oligomerization takes place one proton is transmitted from the 3640 OH group to the oligomeriz
