Sensibilidad Paramétrica y Condiciones Seguras de Operación de la Hidrólisis del Anhídrido Acético en un Reactor Batch

Abstract

The results of a study on the parametric sensitivity of acetic acid production by hydrolysis of acetic anhydride, using acid homogeneous catalysis in a batch reactor, are presented. Dimensionless parameters of mass and energy balances were fitted using experimental data available in the literature that includes the variation of the reaction temperature for different sulfuric acid concentrations (3% to 5%). Then, from the analysis of the intrinsic mathematical properties of the concentration-temperature phase plane, the critical operating conditions were defined. Thus, it was possible to determine the specific values of the safe operating conditions for the catalyzed hydrolysis of acetic anhydride, in the function of catalyst concentration.
