NAPHTHALENE ALKYLATION PROCESS

Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite which contains rations having a radius of...

Beschreibung
Zusammenfassung:	Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite which contains rations having a radius of at least 2.5 .ANG.. Cations of this size may be provided by hydrated rations such as hydrated ammonium, sodium or potassium rations or by organoammonium rations such as tetraalkylammonium rations. The presence of the bulky rations in the zeolite increases the selectivity of the catalyst for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products. The zeolite may be treated to reduce its acid activity.
