Abstract
SE OBTIENE UNA MAYOR EFICIENCIA EN UN PROCEDIMIENTO DE OXIDACION DEL CUMENO EN UNA EMULSION ACUOSA ALCALINA QUE UTILIZA UNA CASCADA DE REACTORES MEDIANTE LA SEPARACION DE LA CASCADA DE REACTORES EN 2 ETAPAS, UTILIZANDO LA PRIMERA ETAPA NH{SUB,4}NACO{SUB,3} COMO CARBONATO ACTIVO EN LA ETAPA QUE CONTIENE MENOS DEL 18 % EN PESO DE HIDROPEROXIDO DE CUMENO Y UTILIZANDO NA{SUB,2}CO{SUB,3} COMO CARBONATO ACTIVO EN LA ETAPA QUE CONTIENE MAS DEL 18 % EN PESO DE HIDROPEROXIDO DE CUMENO. LOS ACIDOS ORGANICOS SON NEUTRALIZADOS DE FORMA EFICIENTE POR INYECCION DIRECTA DE AMONIACO EN UNA CORRIENTE DE RECICLADO. UN LAVADO CON AGUA A CONTRACORRIENTE DE LA SEGUNDA ETAPA INCREMENTA TAMBIEN LA EFICACIA DEL PROCEDIMIENTO AL ELIMINAR IMPUREZAS NO DESEADAS. EL CONTROL DE PH DEL PROCESO MEJORA LA EFICIENCIA Y REDUCE LOS NIVELES DE IMPUREZAS.
