There is added to the atmosphere above the reaction mixture over a 4 to 5 hour period, 50.8 kg (2.983 k moles) of ammonia gas, while maintaining a temperature of 10° to 45° C., to a mixture of 1225 kg of a 22.3% solution of cyanuric chloride (273.1 kg; 1.481 k moles) in toluene at 45° C. There is obtained a thick reaction mass of 2-amino-4,6-dichloro-1,3,5-triazine and ammonium chloride. The mixture is cooled to 5°-10° C. and 334 kg of methanol is added. There is obtained a mixture which is referred to hereinafter as the "first mixture."
