Abstract

La,NaY zeolite (I) is prepared by contact-induced ion exchange between solid LaCl3·7 H2O and NaY zeolite powder. La,NaY (I) is investigated by X-ray diffraction, 27AI MAS n.m.r., 29Si MAS n.m.r., 23Na MAS n.m.r., and i.r. spectroscopy after various treatments. Results are compared with those obtained employing a conventionally exchanged La,NaY sample (76). It is shown that the behavior of La,NaY zeolites obtained via either route are very similar except for a somewhat lower thermal stability of the La,NaY (I) after heat-treatment at high temperature (850 K), treatment with water, and repeated high-temperature treatment. The catalytic performance of La,NaY (I) and La,Nay (74) is almost identical when tested for acid-catalyzed selective disproportionation of ethylbenzene.
