A method of treating an aqueous or non-aqueous dfsystem is disclosed which comprises adding to the system a thiolan of the formula
wherein each of X and Y, which may be the same or different, represents fluorine, chlorine or bromine, in combination with a sulphone of the formula:
R₁ - SO₂ CH = - R₂
in which R₁ represents an optionally halogenated alkyl radical or an optionally subsituted aryl radical, R₂ represents a cyano of amidocarbonyl radical and X represents a halogen atom.
本发明公开了一种处理水性或非水性 df 系统的方法,该方法包括向该系统中加入式中 X 和 Y(可以相同或不同)各自代表氟、氯或溴的硫杂环戊烷与式中 R₁ - SO₂ CH = - R₂ 的砜结合,其中 R₁ 代表任选卤代烷基或任选亚甲基芳基,R₂ 代表氨基羰基的氰基,X 代表卤素原子。
