PURPOSE:To produce an ethylated naphthalene in high yield while suppressing tar formation of naphthalenes by ethylation of a naphthalene with ethylene as an ethylating agent in the presence of extremely stable Y zeolite. CONSTITUTION:In production of an ethylated naphthalene shown by the formula (Et)n-Naph-(R)m (in the formula, Naph shows naphthalene ring, R shows hydrogen, methyl group or isopropyl group, Et shows ethyl group, m shows 0-7 integer and n shows 1-8 integer with proviso that 1<=m+n<=8), a naphthalene shown by the formula Naph-(R)m(in the formula, Naph, R and m are as shown above) is reacted with ethylene as an alkylating agent in the presence of extremely stable Y zeolite. |
