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.

Disclosed herein are flame suppression compounds and methods of use thereof. The compounds include unsaturated fluorocarbons appropriate for use in fire protection applications.
摘要:
The disclosure describes a process for dehalogenation of chlorofluorocompounds. The process comprises contacting a saturated chlorofluorocompound with hydrogen in the presence of a catalyst at a temperature sufficient to remove chlorine and/or fluorine substituents to produce a fluorine containing terminal olefin.
