ABSTRACT:
The invention provides a process for producing 2-methylnaphthalene by isomerization of 1-methylnaphthalene in which a Y zeolite having a unit cell constant of less than or equal to 24.37 .ANG. (10.sup.-10 m) is used as an isomerization catalyst.
Since the isomerization is effected by the use of the inventive heterogeneous solid catalyst which has a long catalyst life, 2-methylnaphthalene is produced from 1-methylnaphthalene efficiently with less cost and handling steps for regeneration or exchange of the catalyst.
