摘要
Abstract
The intermediate N-ethoxylcarbonyl isothiocyanate was synthesized from ethyl chloroformate and sodium thiocyanate by nucleophilic substitution reaction and isomerization. Then using this intermediate with 1,6-diaminlhexane as raw materials, the target product N,N'-diethoxycarbonyl-N",N' "-(1.6-hexylidene) dithiourea was obtained by nucleophilic addition reaction. The compound was characterized by elemental analysis, infrared spectrum, 'HNMR and I3CNMR. The solution of the compound was mixed with Cu2+, Ni2+, Fe3+ solution respectively, and the changes of the absorbance of three compound solutions via UV-Vis spectrophotometer were determined. The precipitate of the compound reacting with Cu2+ ion was analyzed through infrared spectrum. The results show that this dithiourea with new structure can react with three ions separately, and has a best selectivity to Fe3+. Compared with the IR spectral data of compound, the structure of the precipitate is of annular chelate.关键词
