Compositions containing adducts and surfactants

摘要

Compositions containing one or more surfactants in combination with sulfuric acid and one or more of certain chalcogen-containing compounds in which the chalcogen compound/H2SO4 molar ratio is below 2. These compositions contain the mono-adduct of sulfuric acid which is herbicidally active for controlling vegetation. Suitable chalcogen-containing compounds have the empirical formula wherein X is a chalcogen, each of R1 and R2 is independently selected from hydrogen, NR3R4, and NR5, at least one of R1 and R2 is other than hydrogen, each of R3 and R4 is hydrogen or a monovalent organic radical, and R5 is a divalent organic radical. The surfactant-containing compositions are particularly useful for the treatment of materials containing lipophilic substances.
