<p>The present invention relates to a process for producing succinic acid using a highly efficient reaction system. More specifically, the present invention relates to a process for producing succinic acid using a highly efficient reaction system comprising a batch type reaction system and a circulation type reaction system, in which a maleic anhydride and water are used as reactants, the process comprising: a batch reaction step of feeding the reactants and a catalyst to a batch type reaction system (12) and subjecting the reactants to primary hydrogenation by supplying hydrogen; a circular reaction step of circulating the reactants that have passed through the batch reaction step to a circulation type reaction system (13) installed to form a closed circuit with the batch type reaction system (12) and subjecting the reactants to secondary hydrogenation by supplying hydrogen to the circulation type reaction system(13) ; and a discharging step of stopping the circulation to the circulation type reaction system (13) and discharging the resulting product within the batch type reaction system (12) to the outside .</p> |
