| titleOfInvention | Production of 3-pentenenitrile by hydrocyanation of butadiene |
| abstract | [Chemical 1] A continuous process for the production of 3-pentenenitrile comprising: (a) contacting a hydrogen cyanide-containing feed, a butadiene-containing feed, and a catalyst precursor composition in a reaction zone, wherein the catalyst precursor composition is And at least one bidentate phosphite ligand selected from one of the groups represented by structures I and II, wherein R 1 and R 5 are independently C 1 is selected from the group consisting of hydrocarbyl ~C 5, R 2, R 3 , R 4, R 6, R 7 and R 8 is selected from the group consisting of H and C 1 -C 4 hydrocarbyl independently, wherein The same reference symbols shall have the same meaning unless expressly limited, and (b) about 95% or more of the hydrogen cyanide is changed to produce 3-pentenenitrile and 2-methyl-3-butene Maintaining the residence time in the reaction zone for a time sufficient for the reaction mixture of rils to occur, wherein the concentration of 2-methyl-3-butenenitrile is kept below about 15% by weight of the total weight of the reaction mixture. A featured method is provided. |
