Abstract

PROCEDIMIENTO PARA LA OBTENCION DE UN AGLOMERANTE A BASE DE RESINA DE FURANO PARA ARENAS DE MOLDEO Y MACHOS. SE PRECONDENSA UREA CON FORMALDEHIDO EN PRESENCIA DE ALCOHOL FURFURILICO, SEGUIDO DE RETICULACION EN PRESENCIA DE ACIDOS FUERTES Y DE UN CATALIZADOR ACIDO TAL COMO ACIDO TOLUENOSULFONICO. LA PRECONDENSACION SE VERIFICA EN PRESENCIA DE UN EXTENDEDOR TIPO SORBITOL, QUE SUSTITUYE TOTAL O PARCIALMENTE AL ALCOHOL FURFURILICO, ESTANDO DICHO EXTENDEDOR PARCIALMENTE SUSTITUIDO, EN CASO DADO, Y PUDIENDO CONTENER UNA CANTIDAD MENOR DE ALCOHOLES DE AZUCARES DI- Y/O OLIGOMERICOS DERIVADOS DE HEXITOL.
