Azeotrope-like compositions and their use |
摘要 |
The invention provides azeotrope-like compositions consisting essentially of RfOC2H5, where Rf is a branched or straight chain perfluoroalkyl group having 4 carbon atoms, and an organic solvent selected from the group consisting of: straight chain, branched chain and cyclic alkanes having 6 to 8 carbon atoms; esters having 4 carbon atoms; ketones having 4 carbon atoms; disiloxanes having 6 carbon atoms; cyclic and acyclic ethers having 4 to 6 carbon atoms; chlorinated alkanes having 3 to 4 carbon atoms and chlorinated alkenes having 2 carbon atoms. The compositions are useful for cleaning, as solvents or carriers for coating and as heat transfer materials.
