PROBLEM TO BE SOLVED: To provide a production method for esterified product(s), capable of greatly improving yield, decreasing waste disposal problems and production cost. SOLUTION: This method relates to the production of esterified products containing at least one kind of carboxylic ester from esterifying reactants comprising an alcohol, and an carboxylic acid or an carboxylic anhydride, its process consisting of (a) putting the esterifying reactants into a fixed bed type reactor under specified reaction conditions and (b) reacting the esterifying reactants in the fixed bed type reactor, (c) the above fixed bed type reactor containing a solid acid catalyst, and (d) the reaction conditions being controlled so that (i) the reactants and products can coexist in a gas-liquid two-phase equilibrium state in the fixed bed type reactor and (ii) at least one kind of reactant component forms one phase and at least one kind of product component forms the other phase. |
