| abstract | [Expression 1] The present invention provides a) Ethylene-type unsaturated nitrile, hydrogen cyanide, and catalyst precursor composition having 5 carbon atoms by continuously feeding a) an ethylenically unsaturated nitrile, hydrogen cyanide, and a catalyst precursor composition. Forming a reaction mixture comprising: in the presence of at least one Lewis acid; b) Formula (I) The value for X is about 0.001 so that the value of the quotient Q (where 3PN is 3-pentenenitrile and 4PN is 4-pentenenitrile) ranges from about 0.2 to about 10. X and Z (where X is 2 for all unsaturated nitriles) by selecting a value for Z in the range from about 0.5 / 1 to about 0.99 / 1. Controlling the total feed molar ratio of pentenenitrile, Z being the total feed molar ratio of hydrogen cyanide to total unsaturated nitrile); and c) extracting the reaction product mixture comprising adiponitrile; Wherein the ratio of the concentration of 2-pentenenitrile to the concentration of 3-pentenenitrile in the reaction mixture is in the range of about 0.2 / 1 to about 10/1; And at least one multi-tooth phosphorus-containing ligand; the multi-tooth phosphorus-containing ligand is from a phosphite, phosphonite, phosphinite, phosphine, and mixed phosphorus-containing ligand or a combination of such members And a polydentate phosphorus-containing ligand that gives acceptable results according to at least one protocol of the 2-pentenenitrile hydrocyanation test method and other having 6 carbon atoms A hydrocyanation process for preparing dinitriles is provided. |
