摘要:
The present invention relates to compositions comprising HFC-63-14mcee. The compositions may be azeotropic or azeotrope-like and are useful in cleaning applications, as a defluxing agent, for removing oils or residues from a surface, depositing or removing lubricants from a surface, and as refrigerants or heat transfer fluids in refrigeration systems, air-conditioners and heat pumps.
摘要:
The present invention relates to compositions comprising fluorinated olefins or fluorinated ketones, and at least one alcohol, halocarbon, hydrofluorocarbon, or fluoroether. In one embodiment, these compositions are azeotropic or azeotrope-like. 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.

The present invention relates to compositions comprising fluorinated olefins or fluorinated ketones, and at least one alcohol, halocarbon, hydrofluorocarbon, or fluoroether and combinations thereof. In one embodiment, these compositions are azeotropic or azeotrope-like. In another emebodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.
摘要:
Disclosed is a method for removing residue from a surface comprising: contacting the surface with a composition comprising at least one unsaturated fluorinated hydrocarbon selected from the group consisting of compounds having the formula E- or Z-R1CH═CHR2, wherein R1 and R2 are, independently, C1 to C6 perfluoroalkyl groups, or C1 to C6 hydrofluoroalkyl groups, and recovering the surface from the composition.
摘要:
This invention relates to cleaning compositions comprising unsaturated fluorinated hydrocarbons. The invention further relates to use of said cleaning compositions in methods to clean, degrease, deflux, dewater, and deposit fluorolubricant. The invention further relates to novel unsaturated fluorinated hydrocarbons and their use as cleaning compositions and in the methods listed above.
