Abstract
Activity and selectivity of titanium pillared clay (Ti-PILC) are highe r than those obtained with a zeolite (Y-82) in dehydration of 1-phenyl ethanol. Under hydrogen, 48% conversion and 98.4% selectivity are obta ined on Ti-PILC as compared with 30% conversion and 81.4% selectivity on Y-82 zeolite in the same conditions. Physico-chemical characterizat ions (adsorption of nitrogen and TPD of ammonia) suggests that these r esults may be explained by a better accessibility of the strong acid s ites of the Ti-PILC.
