| description | PURPOSE:To obtain an amino resin from normally liquid alcohol, formaldehyde, melamine, etc., by efficiently discharging the formed water out of the system and effecting the shortening of a reaction time and the stabilization of the resin quality by separating and removing the water in the vapor generated in the reactor in a specified manner. CONSTITUTION:A process for producing an amino resin by reacting under heating a normally liquid alcohol (e.g. methanol) with formaldehyde and melamine and/or urea and/or benzoguanamine in the presence of an acid catalyst, wherein the water in the vapor generated in a reactor 1 is separated and removed by using a polymer membrane 5. |
