1,1,1,2,2,5,5,6,6,6-十氟己烷

反应条件: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The reactor in this Example consisted of a 1.25 inch diameter pyrex tube heated by means of electrical heating tape and an internal thermocouple to measure the temperature inside the tube. The reactor was packed with a mixture of 50 cm3 of 0.5% Pd/Al2O3 (1/8 inch pellets) and 100 cm3 of glass helices for a total bed volume of 150 cm3. The Pd/A12O3 pellets are available from Aldrich Chemical or Engelhard Industries. Effluent from the reactor was condensed into cold traps maintained at -30° C. and -78° C. Hydrogen was passed into the tube at 155 mL/min, while CF3CF2CC12CC12CF2CF3 was metered into the top of the vertically mounted reactor at a rate of about 10 g/h. The temperature inside the reactor during the reduction was 202°-206° C. After a total reaction time of 3.75 h (38.1 g total CF3CF2CC12CC12CF2CF3 added), 20.15 g of product was collected in the cold traps, which was 99% pure according to GC analysis. The product was identified as CF3CF2CH2CH2CF2CF3 (boiling point 66° C., 80% yield) based on nuclear magnetic resonance and mass spectroscopy analysis. heated by means of electrical heating tape condensed into cold traps was 202°-206° C was collected in the cold traps, which
