Caprolactam production process

Extraction and control in the process of caprolactam production

Caprolactam (C₆H.₁₁NO) are the raw material of plastic and nylon 6 fiber engineering.

Caprolactam is a composed of carbon, nitrogen, oxygen and hydrogen compounds, can be made by cyclohexane or phenol.

Normally, caprolactam is generated by oxidation of cyclohexane or produced from phenol or toluene.

The ammoxidation of nitrous oxide, hydroxylamine sulfate.Then in the role of sulfuric acid hydrogenation.Then, hydroxylamine sulfate reaction with cyclohexanone, produce cyclohexanone oxime.Subsequent beckmann rearrangement, the use of caprolactam fuming sulfuric acid.

Visa K - PATENTS^®Online refractometer can be used to measure the first time after the extraction of aqueous caprolactam concentration, to control and maintain a high extraction efficiency.

Refractometer can also be used for evaporation process control.It provides the signal to the controller to the inlet flow to adjust density by changing the evaporator.
