Abstract

MEMBRANAS NUEVAS, UTILES PARA LA SEPARACION DE AROMATICOS DE SUS MEZCLAS CON NO AROMATICOS EN, POR EJEMPLO, UNA CORRIENTE DE ALIMENTACION DE NAFTA, SE CARACTERIZA POR POSEER UN INDICE DE UREA DE APROXIMADAMENTE 20 % POR LO MENOS, PERO MENOS QUE 100 %, UN CONTENIDO EN CARBONO AROMATICO DE 15 % EN MOLES APROXIMADAMENTE POR LO MENOS, UNA CONCENTRACION DE GRUPOS FUNCIONALES POR LO MENOS 10 POR 100 G DE POLIMERO Y UNA RELACION C=O/NH MENOR QUE 8,0. ESTAS MEMBRANAS DE POLIUREA/URETANO MUY AROMATICAS SON MEMBRANAS DE PELICULA DENSA, SIMETRICAS, HECHAS DE LOS CORRESPONDIENTES POLIMEROS DE POLIUREA/URETANO POR TECNICAS DE FUNDICION DE MEMBRANAS PATRON. LOS COPOLIMEROS DE POLIUREA/URETANO PREFERIBLEMENTE SE PRODUCEN POR REACCION DE COMPUESTOS DIHIDROXI Y POLIHIDROXI, TALES COMO POLIETERES Y POLIESTERES QUE TIENEN PESOS MOLECULARES ENTRE 500 Y 5000 APROXIMADAMENTE, CON DIISOCIANATOS O POLIISOCIANATOS ALIFATICOS, ALQUILAROMATICOS O AROMATICOS Y EXTENSORES DE CADENA DE PESO MOLECULAR BAJO, TALES COMO DIAMINAS, POLIAMINAS O AMINOALCOHOLES. LAS MEMBRANAS SON UTILES PARA SEPARAR AROMATICOS DE NO AROMATICOS EN, POR EJEMPLO, REFINERIAS DE PETROLEO Y APLICACIONES QUIMICAS.
