| description | The present application relates to a process for the reduction of 3, 3, 3-trifluoropropyne in 2, 3, 3, 3-tetrafluoropropene. The present invention relates to a method of reducing the concentration of a fluorinated alkyne impurity, such as 3, 3, 3-trifluoropropyne (TFPY), in 2, 3, 3, 3-tetrafluoropropene (HFO-1234yf) comprising 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, in some practices comprising reducing the concentration by at least about 50%.
本申请涉及减少2,3,3,3-四氟丙烯中的3,3,3-三氟丙炔的方法。本发明涉及降低2,3,3,3-四氟丙烯(HFO-1234yf)中的氟化炔烃杂质，例如3,3,3-三氟丙炔(TFPY)的浓度的方法，其包括使这样的混合物与苛性材料，例如氢氧化钠（NaOH）在有效降低氟化炔烃杂质的浓度的条件下接触，在一些实践中包括将浓度降低至少约50%。 |
