2-Hydroxy-1,1,2,3,3-pentahydro-perfluoroalkyl derivatives, their production and use

Abstract

A compound of the formula: ##STR1## WHEREIN Q is a hydrogen atom, --CH.sub.2 CH(OH)CH.sub.2 Rf or a hydrocarbon residue having a valence corresponding to m which may contain one or more of --O--, --COO--, --NH--, --N.dbd. and ##STR2## IN THE CHAIN, R is a hydrogen atom, a hydrocarbon residue or --CH.sub.2 CH(OH)CH.sub.2 Rf and m is an integer of not less than 1, Rf being a perfluoroalkyl group, an .omega.-hydro-perfluoroalkyl group o an .differential.-chloro-erfluoroalkylgroup having 4 to 20 carbon atoms, which is useful as an agent for rendering fibrous materials oleophobic and anti-soiling and may be prepared by reacting a perfluoroalkylpropylene oxide of the formula: ##STR3## wherein Rf is the same as defined above, with a reagent of the formula: Q'(NHR').sub.m wherein Q' is a hydrogen atom or a hydrocarbon residue having a valence corresponding to m which may contain one or more of --O--, --COO--, --NH-- and --N.dbd. in the chain, R' is a hydrogen atom or a hydrocarbon residue, and m is the same as defined above.
