In the process of producing melamine by the thermal decomposition of urea or its derivatives, an improved method for separating the molten material (composed mainly of melamine formed in a pressurized reactor) from the gases (composed mainly of ammonia and carbon dioxide) under nearly the same conditions as prevail in said reactor, and for recovering the by-product gases as pressurized by-product gases, with the crude liquid melamine eliminated therefrom.
