Abstract: The novel urethanes correspond to the formula I below ##STR1## in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water.The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Abstract: Perfluoroalkylacetyl chlorides of the formula ##STR1## wherein R.sub.f represents a straight-chain perfluoroalkyl radical having from 4 to 12 carbon atoms which are prepared by reacting perfluoro alkyl ethanols having general formulaR.sub.f . CH.sub.2 . CH.sub.2 . OH II.wherein R.sub.f has the same meaning as in formula I, with chlorine under exposure to UV irradiation, in the presence of an inert organic solvent, at temperatures of from -20.degree. C to +120.degree. C. These acetyl chlorides are intermediates for the preparation of the corresponding esters with polyglycols which serve as dry cleaning detergents.
