Disclosed herein are processes for the production of hydrofluoroolefins by dehydrofluorination. Also disclosed herein are processes for separation of hydrofluoroolefins from hydrofluorocarbons and from hydrogen fluoride.
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.

CFC replacement solvent compositions, methods of using the same and methods of making the same. These compositions meet or exceed the solvency, flammability, and compatibility requirements for CFC's while providing similar or improved environmental and toxicological properties. These solvent compositions have applications including, but not limited to, oxygen handling, refrigeration or heat pumps, electronics, implantable prosthetic devices, and optical equipment.
