Abstract

Abstract Aliphatic ether compounds having a formula selected from the group consisting of ##EQU1## wherein each of a and d is 2 or 3; each of b, c, e, i, j and k is 0 or 1; each of f and g is 0, 1, 2, or 3; h is 0, 1, or 2; a + b + = 3; d + e = 3; f + g + h = 3; i + j + k = 1; and X is F or Cl; with the provisos that when a and d are both 3, then i is 1, f is 0, 1, or 2, and g is 0, 1, or 3; when g is 2, then f is 1; when c is 1, then f is 3 and k is 0; when j is 1, then c is 1; and when both b and e are 1, then i is 1, are useful as solvents and dispersants for fluorinated materials. In addition, the compounds methyl 1-bromo-1,1,2,3,3,3-hexafluoroisopropyl ether and methyl 1,2-dichloro-1,1,3,3,3-pentafluoroisopropyl ether are useful as inhalation anesthetics.This is a continuation-in-part application of application Ser. No. 295,640 filed Oct. 6, 1972, now abandoned.
