Abstract: Caprolactam is prepared by reacting a solution of 6-aminocapronitrile with water in the liquid phase at elevated temperatures by a process in which (a) an aqueous solution of 6-aminocapronitrile in the liquid phase is heated without the addition of a catalyst in a reactor A to give a mixture I consisting essentially of water, caprolactam and a high-boiling fraction (high boiler), then (b) the water is removed from the resulting mixture I to give a mixture II consisting essentially of caprolactam and the high boilers, then (c) the caprolactam and the high boilers from mixture II are separated from one another by distillation, and then either (d1) the high boilers from stage (c) are fed into the reactor A of stage (a) or (d2) the high boilers are heated similarly to stage (a) in a further reactor B and then worked up similarly to stages (b) and (c) to give further caprolactam, or (d3) the high boilers are heated under reduced pressure in the presence of a base in a reactor C and the reacted mixture is worked up by distillation to give caprolactam.

Abstract: Method for preparing caprolactam by heating 6-aminocapric acid nitrile in the presence of heterogeneous catalysts ans water under elevated pressure, wherein (a) 6-aminocapric acid nitrile or a mixture containing essentially 6aminocapric acid nitrile as well as water and a low-boiling or a high-boiling alcohol is heated in the presence of a heterogeneous catalyst in a reactor A to produce a mixture (I); then (b) mixture (I) is distilled, yielding a head fraction, caprolactam and a bottom product, with any ammonia in mixture (I) being removed prior to distillation; and then (c1) the head fraction is fed into the reactor of step (a), with the head fraction optionally being mixed with the alcohol and/or water and/or 6-aminocapric nitrile used in step (a) before being fed into reactor (A); or (c2) the head fraction, optionally with the bottom product from step (b), is fed into a reactor (B), the first fraction optionally being mixed with the alcohol and/or water and/or 6aminocapric acid nitrile before being fed into reactor (B), and then analogously to step (b) caprolactam is produced by distillation; and either (d1) the bottom product from step (b) is fed into reactor A of step (a); or (d2) optionally water and possibly a low-boiling or a high-boiling alcohol are added to the bottom product which then, analogously to step (a) is heated in a reactor (C) to give a reaction product which is distilled to yield caprolactam; or (d3) water is added to the bottom product which is heated in a reactor (D) without added catalyst to give a reaction product which is distilled to yield caprolactam; or (d4) water and a base are added to the bottom product which is heated in reactor (E) to give a reaction product which is distilled to yield caprolactam.
