The present invention relates to a process for the preparation of melamine, which process comprises at least the following steps: i) feeding methane and ammonia to a pre- reactor which pre- reactor is maintained at a temperature between 700 and 1500 °C whereby a gaseous mixture (i) is formed comprising at least hydrogen cyanide, ii) optionally, purifying mixture (i) thereby forming a mixture (ii) that contains at least gaseous hydrogen cyanide, a. feeding hydrogen cyanide from mixture (i) or (ii) and ammonia, either separately or combined, to a reactor that contains a catalyst and which reactor is maintained at a temperature of 300-500°C, at a space velocity lying between 102 and 106 ml/(g.hr), whereby a gaseous mixture (a) is formed comprising at least melamine, b. optionally, purifying mixture (a) producing a melamine containing mixture (b), c. separating at least a part of the formed melamine thereby forming a mixture (c) and separated melamine.
