| titleOfInvention | Method for preparing 2,3,3,3-tetrafluoropropene |
| abstract | The present invention provides a method for the efficient production of 2,3,3,3-tetrafluoropropene (HFO-1234yf) by a simple and economically advantageous method suitable for implementation on an industrial scale. The present invention (1) in the reactor, (1-1) reacting 1,1,1,2,3-pentachloropropane with an amount of 10 to 100 moles of hydrogen fluoride per mole of 1,1,1,2,3-pentachloropropane; (1-2) Compositional formula: in the presence of chromium oxide represented by CrOm (1.5 <m <3) or fluorinated chromium oxide obtained by fluorination of the chromium oxide; (1-3) in the presence of 0.02 to 1 molar amount of oxygen per mole of 1,1,1,2,3-pentachloropropane; And (1-4) reacting in the gas phase in the temperature range of 320 ° C to 390 ° C, thereby obtaining a reaction product comprising 2,3,3,3-tetrafluoropropene It provides a method for producing 2,3,3,3-tetrafluoropropene. |
