2H, 2H-perfluoroalkylethanoic acids give, under mild conditions, in the presence of alcoholic potassium hydroxide, corresponding enol ethers or ketals in very good yield. The reduction of the acid function of these derivatives and the aminolysis of the corresponding eaters lead to relatively hydrophobic surfactants. These compounds have been tested to determine if they give stable gel-emulsions from fluorocarbons.
