Abstract
Cyclohexylation of naphthalene was studied over four commercial unmodi fied HY zeolites. Approximately equal results were obtained on HY (ZF 515, ZF 520, CBV 720) zeolites. The best results were obtained with cy clohexylbromide as alkylating agent in n-nonane and in n-decane as sol vents at boiling point. Conversion of naphthalene was max. 97%, 2,6-se lectivity 43% and beta,beta'-selectivity 77%.
