Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE PRODUCCION DE DIARIL OXALATO, CARACTERIZADO PORQUE SE SOMETE DICHO DIARIL OXALATO A UNA REACCION DE DESPROPORCION, EN PRESENCIA DE UN CATALIZADOR DE DESPROPORCION, PRODUCIENDO COMO RESULTADO UN DIARIL OXALATO, ELIMINANDO SIMULTANEAMENTE UN SUBPRODUCTO QUE CONTIENE UN DIALQUIL OXALATO. EL PROCEDIMIENTO DE PRODUCCION DE LA PRESENTE INVENCION, ES VENTAJOSO EN CUANTO A QUE LOS TIPOS DE SUBPRODUCTOS SON MENOS QUE EN EL PROCEDIMIENTO CONVENCIONAL DE PRODUCCION DE DIARIL OXALATO Y, POR TANTO, PUEDE UTILIZARSE DE FORMA PRACTICA EN LA INDUSTRIA. LOS DIARIL OXALATOS, COMO EL DIFENIL OXALATO, PRODUCIDOS MEDIANTE DICHO PROCEDIMIENTO, SON MATERIALES INDUSTRIALES MUY IMPORTANTES PARA LA PRODUCCION DE PRODUCTOS QUIMICOS TALES COMO LOS CARBAMATOS.
