Definitions

  • Step B From 10 to 100, preferably from 15 to 60, moles of hydrogen fluoride per mole of trichloroethylene are typically employed in Step B. Again, the reaction product of this stage will normally contain unreacted hydrogen fluoride. Contact times of 1 to 100 seconds, preferably 5 to 30 seconds may be used, typically at 220-350°C and 5 to 20 bars pressure.
  • the activity of a catalyst comprising 22 by weight iron on alumina prepared from an aqueous solution of iron (III) chloride as described above, was also measured.
  • the atomic loading of the 62 w/w zinc and 0.5Z w/w iron on alumina is equal to that of the 6.62 w/w zinc on alumina catalyst (example 7) and the activity of the catalyst of example 7 and examples 3, 5 and 6 are also shown below for the purposes of comparison.
