PROCESS FOR REDUCING 3,3,3-TRIFLUOROPROPYNE IN 2,3,3,3-TETRAFLUOROPROPENE

PROCESS FOR REDUCING 3,3,3-TRIFLUOROPROPYNE IN 2,3,3,3-TETRAFLUOROPROPENE

The invention relates to a process for reducing the concentration of a fluorinated alkyne impurity, such as 3,3,3-trifluoropropyne (TFPY), in 2,3,3,3-tetrafluoropropene (HFO-1234yf) which comprises contacting such a mixture with a caustic material, such as sodium hydroxide (NaOH), under conditions e...

description The invention relates to a process for reducing the concentration of a fluorinated alkyne impurity, such as 3,3,3-trifluoropropyne (TFPY), in 2,3,3,3-tetrafluoropropene (HFO-1234yf) which comprises contacting such a mixture with a caustic material, such as sodium hydroxide (NaOH), under conditions effective to reduce the concentration of the fluorinated alkyne impurity, including in some practices reducing the concentration by at least 50%.
