Abstract

Procedure for obtaining caprolactam by catalytic rearrangement of cyclohexanonoxime in a heated, fluidized catalytic bed, optionally on a support, and where cyclohexanonoxime is introduced in liquid form, characterized in that cyclohexanonoxime, both melted and dissolved in an inert solvent, it is passed through the inner tube of a nozzle, without using a propellant gas, under a pressure between 5 and 150 atmospheres and at a temperature between 50 and 360ºC inside the fluidized bed and concentrically through the outer annular gap is fed a sweep gas stream at an angle that limits the opening angle of the hollow cone of the sprayed liquid to between 15 and 110 °.
