Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE RESINAS DE AMINO-FORMALDEHIDO Y, EN PARTICULAR, PARA LA PRODUCCION DE RESINAS DE IUREA Y FORMALDEHIDO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE HACE REACCIONAR UNA SOLUCION DE FORMALDEHIDO EN AGUA CON UREA, EN UNA RELACION MOLAR DE FORMALDEHIDO A UREA MAYOR QQUE 2,5:1; SEGUNDA, SE CONCENTRA LA SOLUCION PREPARADA HASTA QUE SU CONTENIDO TOTAL DE AGUA SEA MENOR QUE EL 50% EN PESO; TERCERA, SE AÑADE UREA ADICIONAL PARA AJUSTAR LA RELACION MOLAR DE FORMALDEHIDO A UREA, ENTRE 2,0:1 Y 1,1:1; Y POR ULTIMO, SE CONCENTRA ADICIONALMENTE LA SOLUCION SIN PRECIPITACION DE LA RESINA SOLIDA, PARA REDUCIR EL CONTENIDO DE AGUA A UN NIVEL TAL QUE AL ENFRIAR EL PRODUCTO LIQUIDO DE RESINA SE OBTENGA UN SOLIDO FRIABLE.
