Abstract

Preparation and characterisation of new ammonium salts of 1,2,benzisothiozolin-3-one, and their use for preparation of highly concentrated solutions with biocidal properties. Quaternary ammonium salts are prepared by reacting 1,2-benzisothiazolin-3-one with either quaternary ammonium hydroxide, or a quaternary ammonium salt, where typically the anion is represented by halogenide, sulphate, phosphate or carbonate with simultaneous addition of metal hydroxide, typically alkali. Quaternary ammonium salts of 1,2-benzisothiazolin-3-one can be formulated in water solutions or solutions of water miscible solvents, solutions of organic solvents containing water, in proportions by weight between the ammonium salt of 1,2-benzisothiazolin-3-one, water and the organic solvents as (10-90):(0-90). 1,2-benzisothiazolin-3-one is shown to exhibit its known biocidal effect after transformation to the ammonium salt.
