摘要: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.
