ABSTRACT:
The present invention relates to azeotropic or azeotrope-like compositions comprising a fluorinated olefin having the formula E- or Z -C3F7CH═CHC3F7, and at least one alcohol, halocarbon, hydrofluorocarbon, fluoroether, or alkanes and combinations thereof. In one embodiment, the one compound selected from the group consisting of alcohols, halocarbons, fluoroalkyl ethers, hydrofluorocarbons, alkanes is either methanol, ethanol, iso-propanol, n-propanol, trans-1,2-dichloroethylene, cis-1,2-dichloroethylene, n-propyl bromide, C4F9OCH3, C4F9OC2H5, HFC-43-10mee, HFC-365mfc, heptane, or combinations thereof. In another embodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.
