<p>A process for producing a 4-phenyl-4-oxo-2-butenoic ester derivative, characterized by simultaneously or continuously reacting a sulfuric ester, aromatic hydrocarbon, and maleic anhydride derivative. By the process, a 4-phenyl-4-oxo-2-butenoic ester derivative having a high purity is stably provided in a short time at low cost on an industrial scale.</p> |
