实验步骤: A mixture of 24 g of bentazone (IIa), 4.8 g of ammonium carbonate, 220 g of 1,2-dichloroethane and 300 g of water was stirred at 50°-60° C. for 1 hour. The phases were then separated, and the water was removed under reduced pressure and at 50°-60° C. 25.5 g of bentazone-ammonium were obtained. The phases were then separated the water was removed under reduced pressure and at 50°-60° C

实验步骤: A solution of 24 g of bentazone (IIa) in 216 g of 1,2-dichloroethane was treated with 22.5 g of a 20% strength aqueous solution of dimethylamine with stirring at 30°-50° C. After addition was complete, the aqueous phase was separated off at 50°-60° C. and evaporated to dryness under reduced pressure and at 50°-60° C. 28 g of bentazone-dimethylammonium (m.p. 145°-147° C.; purity >99% according to HPLC analysis for bentazone and titration for dimethylammonium) were obtained. After addition the aqueous phase was separated off at 50°-60° C. evaporated to dryness under reduced pressure and at 50°-60° C

实验步骤: A solution of 24 g of bentazone (IIa) in 216 g of 1,2-dichloroethane was treated with stirring at 50°-60° C. with 34 g of ammonia water (5% strength solution of ammonia in water). After addition was complete, the aqueous phase was separated off at 50°-60° C. On cooling the aqueous phase, the bentazone-ammonium was deposited in crystalline form. The solid was separated off at 20° C. by filtration and freed from solvent residues under reduced pressure and at 50° C. 11.8 g of bentazone-ammonium (m.p. 180° C.) were obtained. By evaporating the water from the mother liquor under reduced pressure and at 50°-60° C., a further 13.7 g of bentazone-ammonium were obtained. After addition the aqueous phase was separated off at 50°-60° C On cooling the aqueous phase The solid was separated off at 20° C. by filtration freed from solvent residues under reduced pressure and at 50° C

实验步骤: 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. a suspension being formed The solid was separated off at 20° C. by filtration
