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.

Abstract: Lactams, in particular ϵ-caprolactam, are produced by the hydrolytic cyclization of aminonitriles, in particular 6-aminocapronitrile, in the vapor phase in a plurality of adiabatic fixed bed reaction zones arranged in succession wherein at least a portion of the heat of the exothermic reaction is removed between each of the successive reaction zones. Conducting the reaction in such a manner requires less capital for the reactor itself. It has also been found that the product exiting such a reaction system can be directly fed to a distillation unit without the need of additional cooling or storing.
