| Inhoud: |
A new ecologically friendly synthesis of N-alkyl-O-ethylthioncarbamates from ethyl dixanthogenates, waste material from the xanthate production plant, and monoalkylamines has been performed in this work. Structure determination of the synthesized compounds and also corresponding intermediates has been performed by IR, 1H-NMR and MS spectrometric methods. Residual dixanthogenates and thioncarbamates in waste water have been done by the gas chromatographic method and corresponding standard curve. It was confirmed that the reaction product was not present in water, while the concentration of dixanthogenates has been determined to be under the maximum contamination limit. |
