ABSTRACT:
Long chain alkyl substituted aromatic compounds, particularly alkylated naphthalenes, are produced by the alkylation of aromatics, e.g. naphthalene, with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of a zeolite alkylation catalyst, preferably a large pore size zeolite such as zeolite Y and in the presence of from about 0.5 to 3.0 weight percent water, preferably 1.0 to 3.0 weight percent. The use of the water co-feed increases the selectivity of the alkylation for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products and also increases activity and catalyst stability.
