Abstract (en)
[origin: ES8304929A1] Fluorine-containing alkylsulfobetaines of the general formula < IMAGE > wherein Rf denotes a perfluoroalkyl radical having 3 to 16 C atoms, R1 and R2, which can be identical or different, denote alkyl radicals or hydroxyalkyl radicals having 1 to 4 C atoms, a is zero or 1, b assumes the value 1 when a is equal to 1 and the values 1 to 4 when a is equal to 0, and c is 3 or 4, are described. These are prepared by reacting the corresponding fluorine-containing amines with propanesultone or butanesultone in organic solvents. The compounds are distinguished in particular by high interfacial activity at the interface of water with non-miscible organic liquids and by compatibility with other surfactants. They are suitable for use as aftertreatment agents (auxiliary dispersing agents) in dispersions of fluoropolymers and as components in fire-extinguishing agents.
