摘　　要：以PEG-400为相转移催化剂,在二氯甲烷溶剂中,以对氯苯甲酰氯、硫氰酸铵和乙二胺为原料,合成一种对称的双硫脲化合物双(N-对氯苯甲酰基)N’-乙二胺硫脲(化合物1)。产品经熔点、1H NMR、元素分析及IR光谱等手段进行了表征。利用紫外-可见吸收光谱考察了该硫脲化合物与CH_3COO^-、F^-、C1^-、Br^-、H_2PO_4^-等阴离子的识别作用,发现化合物1只对CH_3COO^-、F^-具有良好的选择性识别作用。实验表明化合物1与CH_3COO^-、F^-通过氢键形成1∶1的稳定配合物。Under the condition of solidliquid phase transfer catalysis,the double(N-p-chlorobenzoyl)N’-ethylene diaminethiourea(compound 1)was synthetised using 4chlorobenzoyl chloride,ammonium thiocyanate and ethylene diamine.Its structures were characterized by melting point,1 HNMR,elementary and IR spectra.The interactions between compound 1 and anions(F-、Cl-、Br-、CH3 COO-、H2 PO4)were investigated by ultravioletvisible absorption spectroscopy in dimethyl sulfoxide.The experimental results showed that the 1∶1 stoichiometry complex was formed between compound 1 and F-,CH3 COOby hydrogenbonding interaction.
