A process is disclosed for producing a fluorinated ether of the formula: R2CHOCF2A, where A is Cl or F, and each R is H, (CF2)nCl, (CF2)nF or (CF2)nH (n is an integer from 1 to 10) by reacting a first reactant of the formula: R2CHOY where Y is H, COF, COCl or COOCHR2 (R is as defined above), a second reactant selected of the formula: CZ2Cl2 or COZ2 where each Z is independently Cl or F (provided that when A is Cl, the second reactant is CZ2Cl2), and HF; and recovering the fluorinated ether from the reaction products. Also disclosed are bis-ethers of the formula: (CF3(CF2)m)2CHOCF2OCH(CF2)mCF3)2, where m is an integer of 0 to 3, which can also be produced by the process. |
