A preparation process of 2-methylnaphthalene （2-MN） was proposed by isomerization, side-stream distillation and extractive distillation. The isomerization of alkyl naphthalene was catalyzed by acid-treated HBEA zeolites, and the 2-MN selectivity of isomerization was 92.70%. Side-stream distillation...
