A process for producing hydrogen cyanide from gaseous acetonitrile comprising reacting the acetonitrile in the presence of an oxygen containing gas while in contact with an oxidation/ammoxidation catalyst at an elevated temperature wherein the improvement comprises producing said gaseous acetonitrile from a mixture of crude acetonitrile contains Henasan impurity and a polymerization inhibiting agent which substantially eliminates the polymerization of the HCN impurity in the crude acetonitrile.
A process of producing hydrogen cyanide comprising:
- a. mixing a polymerization inhibiting agent with crude acetonitrile containing HCN as an impurity to form a mixture, said polymerization inhibiting agent substantially eliminating the polymerization of the HCN impurity in the crude acetonitrile;
- b. heating said mixture to a temperature sufficient to vaporize said acetonitrile;
- and
- c. feeding said vaporized acetonitrile into a fluid bed reactor contain an oxygen containing gas and an oxidation/ammoxidation catalyst to produce hydrogen cyanide.
