High-performance liquid chromatographic separation and identification of alkylxanthate mixtures after derivatisation with dimeric cobalt dithiocarbamates

Abstract

A simple method for the separation and identification of alkylxanthates was developed. The xanthate mixtures were first reacted with Co₂(Et₂DTC)₅BF₄ to form the cobalt complexes Co(Et₂DTC)₂(RXAN)(where DTC = dithiocarbamate). The cobalt complexes were separated by reversed-phase high-performance liquid chromatography and the components were identified from their relative retention times.
