Perfluoroalkylether tertiary alcohols

摘要

Perfluoroalkylether (PFAE) tertiary mono- and poly-alcohols of the general structure: <IMAGE> wherein R1 and R3 represent perfluoroalkyl groups having from one to fifty carbon atoms or PFAE groups having 2-50 carbon atoms and 1-49 oxygen atoms; R2 represents a PFPAE group having 3-50 carbon atoms and 1-48 oxygen atoms; A represents perfluoroalkylene groups containing 2-30 carbon atoms or perfluoroalkyleneether groups having 2-30 carbon atoms and 1-29 oxygen atoms; and n is an integer having a value ranging from zero to ten; and wherein the alcohol contains at least 12 carbon atoms per molecule. The perfluoroalkylether (PFAE) tertiary mono- and poly-alcohols are mixed with perfluoropolyalkylether fluids in an amount ranging from 0.01 to 1.00 weight percent to provide fluids having improved antiwear properties.
