- Abstract
It has been shown that Dowex DR-2030 provides 100 % conversion of cyclohexanone oxime (17 wt. % solution in DMSO) with 80-85 % ε-caprolactam yield at 100-120 °C (LHSV = 1 h-1). By the results on quantumchemical simulation of Beckmann rearrangement of cyclohexanone oxime, DMSO promotes lowering of energy barrier of the reactions of oxime protonation and deprotonation of formed caprolactam.
