Patent number: 8350094Abstract: A method of making a fluorinated ether includes combining, in a polar aprotic solvent: a fluorinated alcohol represented by the formula X—Rf1CH2OH, and a fluorinated sulfonate ester represented by the formula Rf2CH2OS(?O)2Rf3, and base; and obtaining a fluorinated ether represented by the formula Y—Rf1CH2OCH2Rf2—Y. Rf1 is selected from perfluorinated C1-C10 alkylene groups having from 1 to 10 carbon atoms and partially fluorinated C1-C10 alkylene groups, and derivatives thereof having catenated heteroatom(s). X represents H, F, or an HOCH2— group. Rf2 is selected from perfluorinated C1-C10 alkyl groups and partially fluorinated C1-C10 alkyl groups, and derivatives thereof having catenated heteroatom(s). Rf3 is a C1-C4 alkyl group. Y represents H, F, or an Rf2CH2OCH2— group. A variant method, useful for preparing symmetric fluorinated ethers, is also disclosed. The present disclosure also provides fluorinated ethers preparable according to the methods.Type: GrantFiled: June 27, 2011Date of Patent: January 8, 2013Assignee: 3M Innovative Properties CompanyInventors: Richard M.
