摘要： A PROCESS FOR RECOVERING MELAMINE FROM HOT SYNTHESIS GASES CONTAINING MELAMINE, NH3 AND CO2 IS DISCLOSED WHEREIN THE HOT SYNTHESIS GASSES ARE CONTACTED WITH AN AQUEOUS SOLUTION OF AMMONIUM CARBAMATE. THE AMMONIUM CARBAMATE DECOMPOSES ENDOTHERMICALLY TO NH3 AND CO2 AND COOLS THE SYNTHESIS GASSES THEREBY DESUBLIMING MELAMINE THEREFROM.
