실험 절차

The procedure in Example 1 was repeated to carry out esterification except that mixed solvent containing 10.0 g of trimethyl trimellitate and 2.0 g of methyl benzoate was fed into the reactor. The results of analysis for the reaction product indicated 91.2 mol % yield of-the objective dimethyl 2,6-naphthalene-dicarboxylate based on 2,6-naphthalene-dicarboxylic acid; 96.0% efficiency of equilibrium achievement; and at most 1.0 mol % by-produced dimethyl ether based on methanol that was fed into the reaction system.
