Abstract
SE PRESENTA UN METODO PARA MEJORAR LA DESCOMPOSICION DEL HIDROPEROXIDO DE CUMENO EN FENOL Y ACETONA MEDIANTE UN CATALIZADOR ACIDICO. EL METODO COMPRENDE LA DESCOMPOSICION DEL HIDROPEROXIDO DE CUMENO DE UNA FORMA NO ISOTERMICA EN LA PRESENCIA DE UN EXCESO DE ACETONA MEDIANTE LO CUAL LA RELACION MOLAR DE LA ACETONA CON RESPECTO AL FENOL EN EL REACTOR DE DESCOMPOSICION ES DE ENTRE 1.1:1 Y 1.5:1. TAMBIEN SE PRESENTA UN METODO PARA MEJORAR LA SELECTIVIDAD DE LA DESCOMPOSICION DEL PEROXIDO DE DICUMIL EN ALFA-METILESTIRENO, FENOL Y ACETONA EN LA PRESENCIA DE UN CATALIZADOR ACIDICO. EL METODO COMPRENDE LA REALIZACION DE LA DESCOMPOSICION A UNA TEMPERATURA ENTRE 80 (GRADOS) Y 110 (GRADOS) C. ASIMISMO SE PRESENTA UN METODO PARA PREPARAR FENOL Y ACETONA A PARTIR DE LA DESCOMPOSICION DE CHP CON UN CATALIZADOR ACIDICO, EL METODO COMPRENDE (A) LA DESCOMPOSICION DEL CHP A UNA CONCENTRACION DE CATALIZADOR ACIDICO ESPECIFICA Y UNA TEMPERATURA ADECUADA MEDIANTE LO CUAL SE FORMA UNA COMPOSICION QUE CONTIENE FENIL, ACETONA Y PEROXIDO DE DICUMIL, LA TRANSFERENCIA DEL PEROXIDO DE DICUMIL A UN REACTOR DE FLUJO EN EL QUE SE PRODUCE LA DESCOMPOSICION DEL PEROXIDO DE DICUMIL EN FENIL, ACETONA Y AMS A UNA CONCENTRACION DE CATALIZADOR ACIDICO INFERIOR Y A UNA TEMPERATURA MAYOR QUE LA CONCENTRACION DE CATALIZADOR Y LA TEMPERATURA DEL PASO (A).
