METHOD FOR PREPARING MELAMINE CYANURATE

摘要

The invention relates to organic chemistry, specifically to an improved method for preparing melamine cyanurate, which is used in various compositions as a fire retardant. When reacting cyanuric acid and melamine in a molar ratio in the presence of 2-30% water based on the mass of dry reagents at a temperature of from 10 to 100°? in air counterflows at 2-10 kp/cm2, melamine cyanurate with a high percentage yield of end product is produced and with a reduced consumption of energy. A further advantage of the proposed method consists in the possibility of implementing said method in the continuous mode.
