8 g of ammonium nitrate were introduced at 50° C. with stirring into a solution of 26.3 g of bentazone-sodium in 21.7 g of water, and the reaction mixture was subsequently stirred for a further hour. After cooling to 20° C., the precipitate was filtered off, washed twice with 5 ml of ice water in each case and dried under reduced pressure and at 50° C. 18.9 g of bentazone-ammonium of 99% purity were obtained.
