Abstract
La presente invención se refiere a procedimiento para la fabricación de soluciones estabilizadas de formaldehido con metanol, caracterizado porque el material de partida es una mezcla líquida que comprende una proporción de formaldehído comprendida entre 48 y 55 por ciento en peso, una proporción de metanol comprendida entre 20 y 30 por ciento en peso y una proporción de agua comprendida entre 32 y 15 por ciento en peso, dicha mezcla líquida procediendo de una toma efectuada de una instalación para la preparación en continuo de colas y resinas de urea-formaldehído, inmediatamente despues de haber sometido metanol a oxidación catalítica por medio de aire a condensación de los gases provenientes de dicha oxidación catalítica y a separación entre los productos condensados y los gases no condensados.
