NEW METHOD FOR SYNTHESISING Ε-CAPROLACTAM

摘要

The present invention relates to the production of ε-caprolactam by treating cyclohexanone oxime with salts derived from guanidinium cation, and in particular with the tosylate of cyanoguanidine ([CNG][TsO]). The invention of the present application also relates to this salt. ε-Caprolactam is the direct precursor of the polyamide fibre Nylon 6, transforming into said fibre by means of polymerisation.
