摘要：

The synthesis and research of a novel thionocarbamate N,N'-diethoxycarbonyl-O,O'-(1,4-butylidene) dithionocarbamate which contains two ester and two thioamide groups are reported. This compound was characterized by elemental analysis, UV spectrum, infrared spectrum, mass spectrum, and H-1 NMR and C-13 NMR spectroscopy. Additionally, the metal ion-collector interaction in organic solution was put into practice. The results of UV spectroscopic analysis showed that this dithionocarbamate with a new structure exhibited a stronger complex ability with Cu2+ than with Ni2+ or Fe3+. Furthermore, infrared spectroscopic analysis implicated that this dithionocarbamate binds to Cu2+ through both the C=O and C=S groups. Bench-scale flotation tests were also carried out, verifying that it has a higher copper flotation recovery and better selectivity to sulfide ores containing Cu compared with universal collectors.
