N-Vinyl Caprolactam factory mentioned extraction purification

A. Extraction and washing: the N-vinyl-caprolactam reaction solution to be washed is dissolved by adding an organic solvent, and water is added to the organic system for washing.

B Distillation: The organic solution in  Step A is subjected to atmospheric pressure distillation to recover the organic solvent, and then vacuum distillation is performed to obtain a high   content of N-vinyl-caprolactam.

Using extraction method, the most important thing is that the main purification method in this process is only liquid-liquid extraction, and the reaction liquid is directly processed,   eliminating the distillation step, thereby making the China N-Vinyl Caprolactam process and the required equipment more simple and suitable Large industrial production saves production costs; it is worth mentioning that caprolactam, organic solvents and water are reused throughout the process.
