Procedure

The process of producing the surfactant of claim 1 comprising (a) reacting at reflux 2,2,3,4,4,4-hexafluorobutanol and 11-bromoundecanoic acid in presence of methane sulfonic acid as a catalyst and benzene as a solvent to obtain 2,2,3,4,4,4-hexafluorobutyl 11-bromoundecylate and then (b) reacting at reflux 2,2,3,4,4,4-hexafluorobutyl 11-bromoundecylate with pyridine in presence of methanol as a solvent to obtain 2,2,3,4,4,4-hexafluorobutyl 11-pyridylundecylate bromide.
