Abstract

SE REIVINDICA UN PROCEDIMIENTO PARA LA PRODUCCION DE CARBONATOS DE DIALQUILO SUPERIORES DE FORMULA (I) (R 1 O)(R SU P,2 O)CO, EN LA QUE R 1 Y R 2 SON UN RESTO ALQUILO LINEAL O RAMIFICADO, SATURADO, INSATURADO Y/O ALCOXILADO, POR TRANSESTERIFICACION DE CARBONATOS DE DIALQUILO INFERIORES CON ALCOHOLES SUPERIORES EN PRESENCIA DE UN CATALIZADOR. EL PROCEDIMIENTO SE CARACTERIZA PORQUE LA TRANSESTERIFICACION SE REALIZA EN UNA COLUMNA DE REACCION DOTADA DE CUERPOS DE CARGA O INCRUSTACIONES Y PORQUE EL COMPAÑERO DE REACCION SE INTRODUCE A CONTRACORRIENTE. SE OBTIENE PREDOMINANTEMENTE CARBONATOS DE DIALQUILO SIMETRICOS.
