Definitions

  • Isobutene mixtures can not be separated economically by distillation because of the low boiling point difference or the low separation factor between isobutene and 1-butene by distillation. Therefore isobutene is made from technical
  • Hydrocarbons are often obtained by reacting isobutene to a derivative that can be easily separated from the rest of the hydrocarbon mixture, and that the isolated derivative to isobutene and
  • Table 1 conversions, selectivities and temperatures of the cleavage of MTBE according to Ex.
