Abstract

PROCEDIMIENTO PARA LA FABRICACION DE SOLUCIONES ESTABILIZADAS DE FORMALDEHIDO CON METANOL, BASADO EN QUE EL MATERIAL DE PARTIDA ES UNA MEZCLA LIQUIDA QUE COMPRENDE UNA PROPORCION DE FORMALDEHIDO COMPRENDIDA ENTRE 48 Y 55% EN PESO, UNA PROPORCION DE METANOL COMPRENDIDA ENTRE 20 Y 30% EN PESO Y UNA PROPORCION DE AGUA COMPRENDIDA ENTRE 32 Y 15% EN PESO; LA MEZCLA LIQUIDA PROCEDE DE UNA TOMA QUE SE EFECTUA EN UNA INSTALACION PARA LA PREPARACION EN CONTINUO DE COLAS Y RESINAS DE UREA-FORMALDEHIDO, INMEDIATAMENTE DESPUES DE HABER SOMETIDO METANOL A OXIDACION CATALITICA POR MEDIO DE AIRE, A CONDENSACION DE LOS GASES PROVENIENTES DE DICHA OXIDACION CATALITICA Y A SEPARACION ENTRE LOS PRODUCTOS CONDENSADOS Y LOS GASES NO CONDENSADOS. ESTAS SOLUCIONES SON DE APLICACION EN REACCIONES DE FORMALDEHIDO EN LAS QUE SEA DE INTERES LA PRESENCIA DE MENOS AGUA QUE EN SOLUCIONES CONVENCIONALES Y TAMBIEN PARA UTILIZAR EL METANOL PRESENTE, POR EJEMPLO, COMO DISOLVENTE DEL PRODUCTO FINAL OBTENIDO.
