Reaktionsschritte

This test is carried out as in Example 3, feeding to the inlet end of the reactor 1317 Kg/hour of a solution containing 14% by weight of cyanuric chloride in acetone and 492 Kg/hour of an aqueous solution containing 12% by weight of isopropylamine and 8.12% by weight of sodium hydroxide. The inlet temperature of stage (a) is 18° C. and the outlet temperature is 55° C. Stage (b) is carried out under isothermal conditions with a temperature of 55° C. and for this purpose the corresponding part of the reactor is provided with heat exchange means. To the input of stage (b) there is fed 375 Kg/hour of an aqueous solution containing 12% by weight of monoethylamine and 10.64% by weight of sodium hydroxide. The reaction products are recovered at the outlet end of the reactor. The conversion of cyanuric chloride is 99% and the 2-chloro-4-ethylamino-6-isopropylamino-s-triazine thus obtained has a purity of 99%.
