| Abstract: | The effects of pre-heater and pre-polymerization reactor temperatures, reflux rate and material level on product quality were studied during caprolactam pre-polymerization and post-polymerization. The caprolactam pre-polymerization process parameters were optimized as followed:pre-heater temperature maximum 220℃, pre-polymerization reactor temperature 267-272℃, reflux rate 90-95 L/h, material level 50%. |
