  • example
  • More particularly, this invention is an improved process for the purification of crude acetonitrile produced, for example, as a byproduct during the formation of acrylonitrile by the ammoxidation of an olefin such as propylene or the ammoxidation of propane. (google.com)
  • Name
  • The ligand priority numbers are, applying the CIP rules: two chlorides of priority number 1 acetonitrile priority 2 pyridine priority 3 In the trans case the configuration index is 1 giving the name(SP-4-1)-(acetonitrile)dichlorido(pyridine)platinum(II). (wikipedia.org)
  • Material
  • Acetonitrile is also used as a raw material for the preparation of other chemicals used in the chemical and pharmaceutical industry. (google.com)
  • side
  • A method for the purification of crude acetonitrile comprising distilling the crude acetonitrile in a first fractional distillation column at below atmospheric pressure, withdrawing a first side draw fraction comprising acetonitrile, distilling the first side draw fraction in a second fractional distillation. (google.com)
  • 8. The method of claim 1 wherein the crude acetonitrile comprises HCN and wherein the first side draw fraction further comprises HCN and is treated to reduce the amount of HCN contained therein prior to distilling the first side draw fraction in the second distillation column. (google.com)
  • column
  • 9. The method of claim 1 wherein the crude acetonitrile comprises HCN and is treated to remove HCN prior to distillation in the first fractional distillation column. (google.com)
