Process for producing ammonium salts of 3-isopropyl-2,1,3- benzothiadiazine-4-on-2,2-dioxide

A process for producing salts of 3-isopropyl-2,1,3- benzothiadiazine-4-on-2,2-dioxide of general formula (I) (R1-R4 = H, lower alkyl, lower hydroxyalkyl) by reacting bentazone (IIa) in an organic solvent with an amine (IIIa), reacting bentazone (IIa) in an organic solvent virtually immiscible with w...

Beschreibung
Zusammenfassung:	A process for producing salts of 3-isopropyl-2,1,3- benzothiadiazine-4-on-2,2-dioxide of general formula (I) (R1-R4 = H, lower alkyl, lower hydroxyalkyl) by reacting bentazone (IIa) in an organic solvent with an amine (IIIa), reacting bentazone (IIa) in an organic solvent virtually immiscible with water with an amine (IIIa) or an ammonium salt (IIIb) and taking salt (I) up in water or reacting bentazone (IIa) with an ammonium salt (IIIb) or sodium bentazone (IIb) with an ammonium salt (IIIc) in water. Spôsob prípravy solí 3-izopropyl-2,1,3-benzotiadiazin-4-ón- 2,2-dioxidu všeobecného vzorca (I), kde R1 až R4 znamená nezávisle od seba vodík, nižší alkyl alebo hydroxyalkyl, pri ktorom sa nechá reagovať bentazón všeobecného vzorca (IIa) vo vode s amóniovou soľou všeobecného vzorca (IIIb) alebo nátriumbentazón všeobecného vzorca (IIb) s amóniovou soľou všeobecného vzorca (IIIc).ŕ
