En este trabajo, se presentan los resultados de la evaluación, caracterización y estudio cinético de los catalizadores utilizados para la producción de acetato de etilo en un solo paso a partir de etanol.
Se seleccionaron los catalizadores de Paladio metálico soportado en carbón activado en dos composiciones nominales (0.5% y 1.5%), y mezclas binarias de óxidos de Antimonio - Molibdeno y Bismuto Molibdeno, en las proporciones atómicas de Sb: Mo = 2:1 y Bi: Mo = 1:9, La mayor actividad se presentó en los catalizadores de Paladio, mientras que los óxidos resultaron ser más selectivos hacia acetaldehído y ácido acético. La esterificación del etanol sobre Paladio en carbón activado puede representarse mediante un modelo Eley-Rideal, en el cual el oxígeno quimisorbido reacciona con el etanol en fase gaseosa siendo este el paso determinante.
