Abstract
This invention relates to a process for the suppression of 3,3,3-trifluoropropyne during the manufacture of fluorocarbons, fluoroolefins, hydrochlorofluoroolefins. More particularly, this invention is directed to a process to suppress the formation of 3,3,3-trifluoropropyne during processes for the manufacture of HCFO-1233zd(E), HCFO-1233zd(Z), HFO-1234ze(E), and/or HFO-1234ze(Z).
Claims21
A process for preventing the formation of 3,3,3-trifluoropropyne during the manufacture of fluorocarbon compounds, said method comprising the steps of:
- (a) forming a fluorocarbon compound in a reaction process that generates reaction products comprising one or more acids;
- (b) conducting one or more substantially caustic-free bulk acid removal procedures on the reaction products of step (a);
- and
- (c) conducting one or more trace acid removal procedures to remove acids remaining after step (b), thereby preventing the formation of 3,3,3-trifluoropropyne.
