Versuchsvorschrift

Using a 10% toluene solution of 1,5-dimethyltetralin obtained by the above method (A), dehydrogenation was conducted at 400° C. in a hydrogen atmosphere in the presence of a 0.3% Pt/Al2O3 catalyst for dehydrogenation to obtain 1,5-dimethylnaphthalene. Conversion of 1,5-dimethyltetralin was 100%, and selectivity to 1,5-dimethylnaphthalene was 97%.
