In the low pressure route, the reaction is carried out in the vapour phase generally using an alumina catalyst. Urea forms isocyanic acid, which is converted first to cyanamide and then to melamine. In the high pressure process, carried out in the liquid phase without a catalyst, urea forms cyanuric acid which is reacted with ammonia to form melamine. Carbon dioxide and ammonia by-products are recycled to urea., 1) by heating urea and ammonia, the resulting mixture of isocyanic acid and ammonia reacts over a solid catalyst at about 400 °C to form melamine, 2) from cyanamide, dicyanamide or cyanuric chloride, Melamine can be synthesized from urea at 390 - 410 °C: ... The overall reaction is endothermic, requiring 649 kJ per mole of melamine starting with molten urea at 135 °C. The processes themselves may be subdivided into two categories: 1. noncatalytic, high-pressure (> or = to 8 MPa) processes, and 2. catalytic, low-pressure processes (ca 1 MPa). Each type includes three stages: synthesis, melamine recovery and purification, and off-gas treatment., Formulations, Preparations: Grade: min-99%, Consumption Patterns: Over 95% of global output is used to make thermosetting resins for use in laminates, protective coatings, textile finishes and paper coatings with applications in the automotive, appliance, dinnerware, furniture, fabric and wood panelling industries.
