Abstract

UN METODO PARA MINIMIZAR O EVITAR LA PRECIPITACION DEL RODIO DE UN CATALIZADOR COMPLEJO DE RODIO-FOSFITO, EN EL QUE, TRAS LA REACCION DE UN COMPUESTO OLEFINICAMENTE INSATURADO CON MONOXIDO DE CARBONO E HIDROGENO PARA PRODUCIR UN ALDEHIDO, EN PRESENCIA DE UN CATALIZADOR COMPLEJO DE RODIO-FOSFITO SOLUBILIZADO, SE SOMETE A DESTILACION, PARA RECUPERAR EL PRODUCTO DE ALDEHIDO, UNA SOLUCION DEL PRODUCTO DE REACCION QUE CONTIENE EL CATALIZADOR COMPLEJO DE RODIO-FOSFITO SOLUBILIZADO, EL PRODUCTO DE ALDEHIDO Y, ADEMAS, UN POLIMERO ORGANICO QUE CONTIENE GRUPOS FUNCIONALES POLARES SELECCIONADOS ENTRE RADICALES DE AMIDA, CETONA, CARBAMATO, UREA Y CARBONATO, EMPLEANDOSE EL POLIMERO ORGANICO EN UNA CANTIDAD DE APROXIMADAMENTE 0,1-5,0% EN PESO Y LLEVANDOSE A CABO LA DESTILACION A UNA TEMPERATURA DE APROXIMADAMENTE 50-140GC. EL INVENTO ES UTIL EN PROCESOS DE HIDROFORMILACION PARA PRODUCIR ALDEHIDOS, PREVINIENDO LA PRECIPITACION DE RODIO EN FORMA DE RODIO METALICO O DE RACIMOS DE RODIO.
