Abstract

A PROCESS FOR THE OBTAINING OF MELAMINE FROM UREA AND/OR ITS THERMAL DECOMPOSITION PRODUCTS, by heating at 200-450º C and at atmospheric pressure or higher pressure, in the presence of ammonia and using aluminum oxide as a catalyst, characterized in that The catalyst used is a phosphated substance, which otherwise consists entirely or preponderantly of aluminum oxide in free or chemically combined form, the proportion of phosphate corresponding to a content of 0.01-35% by weight of P.
