ABSTRACT:
A catalytic process is provided for the preparation of dialkylnaphthalenes by alkylating a 2-alkylnaphthalene with an alkylating agent having an aliphatic group of from one to five carbon atoms, such as methanol. The catalyst comprises a synthetic zeolite characterized by an X-ray diffraction pattern including interplanar d-spacings at 12.36.+-.0.4, 11.03.+-.0.2, 8.83.+-.0.14, 6.18.+-.0.12, 6.00.+-.0.10, 4.06.+-.0.07, 3.91.+-.0.07 and 3.42.+-.0.06 Angstroms.
