Abstract: This disclosure is directed to novel ethers of the formula:CF.sub.3 CH.sub.a X.sub.b --O--CF.sub.2 CH.sub.c F.sub.d Cl.sub.ewherein X is fluorine, chlorine or bromine, preferably fluorine, a is 1 or 2, b is 0 or 1, a plus b are 2, preferably both a and b being 1, c is 0 or 1, d is 0 to 2, e is 0 to 2, c plus d plus e are 3, preferably each of c, d, and e is 1, and a plus c are 1 or 2, preferably 2, with the proviso that when e is 1 or 2, X is fluorine or bromine, preferably fluorine. The compounds having less than 8 fluorine atoms per molecule are useful as anesthetics, and all of the compounds are useful as solvents and dispersants for fluorinated materials. A highly preferred compound useful as an anesthetic is 1,2,2,2-tetrafluoroethyl 1',1',2'-trifluoro-2'-chloroethyl ether.

Abstract: Aliphatic ether compounds of the formula ##EQU1## wherein Z is CH.sub.3 or Cl, and n is zero when Z is CH.sub.3 and is one when Z is Cl, are useful as inhalation anesthetics.
