| titleOfInvention | Integrated process for nitrile manufacture with enhanced liquid-liquid extraction |
| abstract | Phosphorus-containing ligands are recovered from mixtures comprising 3-pentenenitrile (3PN) and adiponitrile (ADN), using liquid-liquid extraction. ADN is produced by hydrocyanation of 3PN. The ADN is hydrogenated to produce a hexamethyiene diamine (HMD) and at Ieast one byproduct including bis-hexamethylene triamine (BHMT) or 1,2-diaminocyclohexane. At Ieast a portion of the HMD product or byproduct is used to enhance the liquid-liquid extraction to recover phosphorus-containing ligand. |
