Abstract
In accordance with the present invention, processes of synthesizing 3,3,3-trifluoropropyne from 1,3,3,3-tetrafluoropropene, 1-chloro-3,3,3-trifluoropropene, and/or 1,1,1,3,3-pentafluoropropane are provided.
Claims15
A process of synthesizing 3,3,3-trifluoropropyne, the process comprising the steps of:
- providing a solution of 1-chloro-3,3,3-trifluoropropene in tetrahydrofuran;
- and,
- adding potassium tert-butoxide to the solution to yield the 3,3,3-trifluoropropyne.
A process of synthesizing 3,3,3-trifluoropropyne, the process comprising the steps of:
- providing a compound selected from the group consisting of 1,3,3,3-tetrafluoropropene, 1-chloro-3,3,3-trifluoropropene, and 1,1,1,3,3-pentafluoropropane;
- mixing the compound with a solvent to make a first mixture;
- adding sodium amide to the first mixture to make a second mixture;
- adding hydrochloric acid to the second mixture to yield the 3,3,3-trifluoropropyne.
