A two-phase kinetic model was implemented for analysing conventional epoxidation, using a percarboxylic acid generated in situ through adding hydrogen peroxide in a two-phase system having a homogeneous catalyst. Data was adjusted using the least square method (0.88 correlation coefficient). The simulation closely predicted oxirane oxygen content values, especially during the first stage of reaction and deviation at the end of epoxidation due, possibly, to different degradation reactions.
Se implementa un modelo cinético de dos fases para el análisis de un proceso convencional de epoxidación, utilizando un ácido percarboxílico generado in situ mediante la adición de peróxido de hidrógeno, en un sistema de dos fases usando un catalizador homogéneo. Los datos obtenidos se ajustan mediante el método de mínimos cuadrados (obteniendo un coeficiente de correlación de 0,88). En general, la simulación predice cercanamente los valores de contenido de oxígeno oxirano, en especial durante la primera etapa de reacción, y una desviación hacia el final de la epoxidación debida posiblemente a las múltiples reacciones de degradación.
