Abstract: A process for the recovery of caprolactam from oligomers and/or polymers of caprolactam, which comprises the following steps: a) treatment of oligomers and/or polymers of caprolactam with from 1 to 20 parts by weight of water per part by weight of oligomer and/or polymer at a temperature of from 200 to 350 DEG C under superatmospheric pressure at a residence time of from 0.5 to 10 hours with formation of an aqueous reaction mixture containing polycaprolactam, monomeric caprolactam and oligomers thereof, and b) passing the aqueous reaction mixture obtained in a) into an aluminium oxide fluidised bed at a temperature of from 250 to 400 DEG C to give a mixture of steam and caprolactam.
