Embodiment Construction

[0008] Below, the present invention will be further described in conjunction with the process flow chart of the present invention.

[0009] Cyclohexylimine is produced from caprolactam by catalytic hydrogenation reaction in a three-phase bed, and its reaction equation is The companion is water. First, the solid caprolactam is heated to 50°C-100°C in the melting tank 1 until it melts, and then pumped into the reactor 2 through a metering pump. After the hydrogen is heated, it is introduced into the reactor 2 from the gas distributor at the bottom of the reactor. Under the temperature of ℃-260℃ and the pressure of 10kg / cm2, under the conditions of catalyst and white oil, the reduction reaction between hydrogen and caprolactam occurs, and the generated cycloheximide enters the heat exchange together with the unreacted hydrogen in the form of gas Heat exchange with the circulating gas at 30-60°C in device 3. During this process, part of the caprolactam and solvent entrained in ...
