Abstract: An esterification reaction apparatus and an esterification reaction method, the esterification reaction apparatus comprising a reaction tank having an accommodation part, in which a raw material containing carboxylic acid and alcohol is accommodated, a heating unit configured to individually heat partition regions that are partitioned into N regions in a vertical direction of the accommodation part, and a controller configured to control the heating unit so that only the partition regions in which a liquid is accommodated among the N partition regions are heated, thereby performing an esterification reaction of the raw material.
