Abstract
A process for rapidly cooling gases which contain caprolactam vapor and which have been obtained by catalytic rearrangement of cyclohexanone-oxime in the gas phase in the presence of a supported catalyst containing boric acid, wherein a finely divided coolant at from 90.degree. to 200.degree. C. is fed into a cooling zone from above, gases which are at 330.degree.-400.degree. C. and contain caprolactam vapor are introduced radially at high speed through nozzle orifices over the downstream portion of the cooling zone, and are cooled to 100.degree.-200.degree. C. by thorough mixing with the finely divided coolant, and the cooled mixture is discharged.
