277 °C

The same catalyst was used from Example 4 above. The reactor was cooled to 277° C. The alcohol (CF3CF2CH2OH) flow of 0.49 mL/hr (2.0 sccm, 3.3×10-8 m3 /s), the COCl2 flow of 3.0 sccm (5.0×10-8 m3 /s), the HF flow of 7.0 sccm (1.2×10-7 m3 /s), and an N2 flow of 2 sccm (3.3×10-8 m3 /s) were begun. The gaseous effluent was analyzed by GCMS and found to be 89.3-90.5% CF3CF2CH2F over a 2 hour period with no evidence for catalyst deactivation.
