Procedure

In addition, 92.21 g (0.500 mole) of cyanuric chloride and 50.41 g (0.600 mole) of sodium hydrogen carbonate were added in this order to 800 ml (13.73 moles) of ethanol kept at 5° C. with mechanical stirring and the mixture was reacted at this temperature for 8 hours with stirring. The resulting solution was poured into 650 g of ice-water and the precipitated white substance was immediately collected by filtration with suction. The substance was washed with 200 ml of water (0° C.) two to three times and dried in a vacuum dryer. It was recrystallized from petroleum ether to give b 2,4-dichloro-6-ethoxy-s-triazine as a colorless solid substance.
