Abstract

UN PROCEDIMIENTO PARA PREPARAR UN CATALIZADOR, EN DONDE SE IMPREGNA UN PORTADOR DEL CATALIZADOR CON COMPUESTOS SOLUBLES EN AGUA DE PALADIO Y ORO, SEGUIDOS POR LA FIJACION Y LA REDUCCION ENTONCES, DE LOS COMPUESTOS FIJADOS DE PALADIO Y ORO AL METAL DE PALADIDO Y ORO, SEGUIDO POR LA IMPREGNACION DEL PORTADOR CON UNA SEGUNDA CANTIDAD DE UN COMPUESTO SOLUBLE EN AGUA DE ORO. SE FIJA LA SEGUNDA CANTIDAD DE COMPUESTO DE ORO, REDUCIDA ENTONCES A METAL DE ORO. SE IMPREGNA ENTONCES EL CATALIZADOR CON UN ACETATO DE METAL ALCALINO, COMO UN ACETATO DE POTASIO. EL CATALIZADOR PUEDE EMPLEARSE PARA SINTETIZAR ESTERES INSATURADOS, COMO UN ACETATO DE VINILO.
