ABSTRACT:
A process for manufacturing an alkenyl aromatic compound which is an industrially valuable compound as a raw material for the manufacture of naphthalenedicarboxylic acid, a highly useful raw material of polymers. The process comprises reacting an alkylbenzene and 1,3-butadiene in the presence of (a) metallic sodium, (b) at least one compound selected from the group consisting of salts of potassium, salts of rubidium, and salts of an alkaline earth metal, and (c) an aromatic compound capable of producing a charge-transfer complex together with metallic sodium. High purity alkenyl aromatic compound can be manufactured at a high yield using a simple procedure.
