The nitrosation of cyclohexanecarboxylic acid (CCA) with nitrosyl sulfuric acid is an important industrial process to produce ε-caprolactam. The experiments showed that there also existed a parallel reaction between CCA and SO3 as well as an intercrossing reaction between caprolactam and nitrosyl sulfuric acid
except for the nitrosation of CCA. A reaction kinetics model of the process was proposed
and the model parameters were indirectly determined by the results from the analysis-synthesis experimental design assuming the reactions in the nitrosation system having no influence on each other.This model not only could explain the control parameters in the industrial process
but also could support the optimization of the industrial process.
