反応手順
1.7-3 g of ammonia were introduced as a gas with stirring at 20°-50° C. into a solution of 24 g of bentazone (IIa) in 2376 g of 1,2dichloroethane, a suspension being formed. The solid was separated off at 20° C. by filtration and freed from solvent residues under reduced pressure. 25.4 g of bentazone-ammonium (m.p. 180° C.) were obtained.
