    Abstract: A process for making alkyl 6-aminocaproate by hydroformylating 3-pentenenitrile to produce 3-, 4-, and 5-formylvaleronitrile (FVN mixture), converting the FVN mixture to alkyl 3-, 4-, and 5-cyanovalerate by either oxidative esterification of the FVN mixture or oxidation of the FVN mixture followed by esterification; isolating alkyl 5-cyanovalerate; and hydrogenating the alkyl 5-cyanovalerate to produce alkyl 6-aminocaproate. The resulting alkyl 6-aminocaproate can be cyclized to produce caprolactam.
