Reaction Conditions:

with aluminum(III) oxide at 400; under 750.075 Torr; for 10 h;Gas phase;

Steps:

14

10 ml of the Al2O3 prepared by the above method was charged in a tubular reactor made of Incon alloy having an outer diameter of 1/2 inch and an internal volume of 30 ml. The reaction conditions were as follows: a reaction temperature of 400 °C, a contact time of pentafluoropropionamide of 100 s, and a reaction pressure of 0.1 MPa. The reaction stream from the reaction tube first flows through the Teflon bottle for condensation, the solid remains at the bottom of the bottle, and then the moisture is removed through the drying tube, and then the reaction stream enters the 316 material 200 mL small cylinder to collect the gas phase in the reaction system. The product pentafluoropropionitrile was continuously collected for 10 hours to obtain 23.4 g of pentafluoropropionitrile, the purity was 99.0% (GC analysis), and the yield of pentafluoropropionitrile was 99.6%.
