Summary:PURPOSE:To industrially obtain a naphthalenedicarboxylic acid as well as a benzonitrile compound both in high yield and purity. CONSTITUTION:A reaction vessel is charged with 2,6-naphthalene dinitrile and benzoic acid as raw materials so as to be (1:13.1) in the molar ratio followed by setting the reaction temperature and distilling column temperature at 250 deg.C and 200 deg.C, respectively, and carrying out a reaction at the atmospheric pressure for 4hr. After completing the reaction, the reaction liquor is subjected to suction filtration under heating at 140 deg.C, and the resultant cake is cooled to room temperature and washed with acetone and then dried at room temperature.
