PRODUCTION OF 2-SUBSTITUTED 6-ISOPROPYLNAPHTHALENE

摘要

PURPOSE:To obtain the title compound in an industrially advantageous way by isopropylation with propylene of a 2-substituted naphthalene in the presence of Y-type zeolite. CONSTITUTION:The objective compound can be obtained by reaction (isopropylation) with propylene pref. at 80-160 deg.C for 30min to 10hr of a 2- substituted naphthalene of the formula (R is H or methyl) (e.g. 2-naphthol, 2-methoxynaphthalene) in the presence of Y-type zeolite (pref. ultrastable one) pref. at 0.1-60wt.% based on the raw material.
