Abstract

Chemically modified microporous materials can be prepared as robust catalysts suitable for application in vapor phase processes such as Friedel-Crafts alkylation. In the present paper we have investigated the use of rare earth metal $(Ce^3^+, La^3^+, RE^3^+, and Sm^3^+)$ exchanged Na-Y zeolites as catalysts for the alkylation of benzene with long chain linear 1-olefin; 1-dodecene. Thermodesorption studies of 2,6-dimethylpyridine adsorbed catalysts (in the temperature range 573 to 873 K) show that the rare earth zeolites are highly Brönsted acidic in nature. A perfect correlation between catalyst selectivity towards the desired product (2-phenyldodecane) and Brönsted acid sites amount has been observed.
