    Abstract: Manufacture of formaldehyde by oxidative dehydrogenation of methanol in the presence of a silver catalyst using methanol obtained from a condensate derived from the evaporation of aqueous reaction mixtures in the synthesis of urea resins and then treated with caustic soda solution under specific conditions of temperature, pressure, residence time and initial formaldehyde concentration. The formaldehyde obtained is a disinfectant, tanning agent, reducing agent and starting material for the manufacture of synthetic resins, adhesives and plastics.
