ABSTRACT:
The invention provides azeotrope-like compositions consisting essentially of R.sub.f OCH.sub.3, where R.sub.f is a branched or straight chain perfluoroalkyl group having 4 carbon atoms, and one or more organic solvent(s) selected from the group consisting of: straight chain, branched chain and cyclic alkanes containing 6 to 8 carbon atoms; cyclic and acyclic ethers containing 4 to 6 carbon atoms; ketones having 3 carbon atoms; chlorinated alkanes containing 1, 3 or 4 carbon atoms; chlorinated alkenes containing 2 carbon atoms, alcohols containing 1 to 4 carbon atoms, partially fluorinated alcohols containing 2 to 3 carbon atoms, 1-bromopropane, acetonitrile, HCFC 225ca (1,1,-dichloro-2,2,3,3,3-pentafluoropropane and HCFC- 225cb (1,3-dichloro-1,1,2,2,3-pentafluoropropane).
