Abstract

LA INVENCION ES DEL CAMPO DE LA QUIMICA DE LOS POLIMEROS. LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE OBTENCION DE POLIOLES, QUE CONSISTE EN UNA PRIMERA ETAPA EN HACER REACCIONAR GLICOLES, ES DECIR PLURIALCOHOLES DE FUNCIONALIDAD AL MENOS IGUAL A DOS (MEG, DEG, DPG,...) SOBRE POLIETILENOTEREFTALATO (PET) EN PRESENCIA DE UN CATALIZADOR (CAT) DE TRANSESTERIFICACION (MEG, DEG, DPG,...) SOBRE POLIETILENOTEREFTALATO (PET) EN PRESENCIA DE UN CATALIZADOR (CAT) DE GLICOLISIS Y, EN UNA ULTIMA ETAPA, EN DESTILAR LOS GLICOLES LIBRES. EL PROCEDIMIENTO QUE SE CARACTERIZA PORQUE UNA ETAPA POSTERIOR A LA PRIMERA Y ANTERIOR O SIMULTANEA A LA ULTIMA ETAPA, COMPRENDE LA DESACTIVACION DEL CATALIZADOR DE GLICOLISIS POR UN AGENTE DESACTIVANTE (DES). COMO EJEMPLO, EL CATALIZADOR (CAT) DE LA REACCION DE GLICOLISIS ES UNO DE LOS AGENTES DEL GRUPO QUE COMPRENDE EL ACETATO DE ZINC Y EL ACETATO DE MANGANESO, LAS AMINAS COMO LA TRIETILAMINA Y LA TRIBUTILAMINA Y EL AGENTE DESACTIVANTE ELEGIDO ES EL ACIDO FOSFORICO A85 %. EL PROCEDIMIENTO LLEVA DIVERSAS VARIANTES UNA DE LAS CUALES LLEVA EL GLICEROL COMO UNO DE LOS PLURIALCOHOLES. APLICACION EN EL RECICLAJE DE LOS POLIETILENOTEREFTALATOS UTILIZADOS COMO MATERIALES DE EMBALAJE.
