Abstract

EL PROCEDIMIENTO UTILIZA UN MATERIAL DE PARTIDA QUE 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.
