Abstract: A process for the preparation of N-phenyl(pyridyl)sulfonyldiamides by reacting a 2-aminobenzoic acid (nicotinic acid) derivative with sulfur trioxide, chlorosulfonic acid or an adduct of sulfur trioxide with a tertiary amine in the presence of a diluent and of a tertiary amine, and reacting the resulting sulfamate with a primary amine and a phosphorus halide, or by reacting a 2-aminobenzoic acid (nicotinic acid) derivatives with an N-alkyl(cycloalkyl)sulfamic acid or a salt of this acid in the presence of a diluent and of a phosphorus halide.

Abstract: PCT No. PCT/EP94/02708 Sec. 371 Date Feb. 15, 1996 Sec. 102(e) Date Feb. 15, 1996 PCT Filed Aug. 13, 1994 PCT Pub. No. WO95/06036 PCT Pub. Date Mar. 2, 1995A process for preparing pyrazole and its derivatives of the formula I I where R1, R2, R3 and R4 are each hydrogen, halogen, nitro, carboxyl, sulfonyl or C-organic radicals, from alpha,beta-unsaturated carbonyl compounds of the formula II II and hydrazine or hydrazine derivatives of the formula III H2N-NHR4 III wherein, initially without additional diluent, an alpha,beta-unsaturated carbonyl compound of the formula II is reacted with hydrazine or a hydrazine derivative of the formula III, and the resulting reaction mixture is reacted in another step with a mixture of sulfuric acid and iodine or a compound which liberates iodine or hydrogen iodide.

Abstract: 3-Isopropyl-2,1,3-benzothiadiazin-4-one-2,2-dioxide (bentazone) is isolated from waste water, originating from its preparation and working up, by treating the waste water with an acid to bring the pH initially to 7.5-9.5, adding 0.2-0.5% by volume, based on the waste water, of a 40-60 percent strength by weight aqueous bentazone salt solution and heating the mixture for 15-30 minutes at 75 DEG -110 DEG C. The solution thus treated is then cooled and brought to pH 1-3 with a mineral acid, whereupon the bentazone precipitates in a form which can be filtered off.
