Abstract
The invention relates to a method and a device for producing melamine by means of the thermal conversion of urea. The invention is characterized in that: a) urea is reacted to form melamine at least partially under reaction conditions wherein an educt, an intermediate and/or an end product are present in a supercritical state; and b) the mixture consisting of at least one educt, an intermediate and/or an end product essentially forms a homogeneous phase and all educts, intermediates, and/or end products are in a complete solution. The single-phase reaction results in an especially efficient reaction.
