摘要
合成了一种含二硫代氨基甲酸基团的酸性缓蚀剂——三乙烯四胺基双(二硫代甲酸钠)(DTC-TETA)。采用了红外光谱及元素分析手段对DTC-TETA的结构进行表征。在DTC-TETA的红外光谱图中,在1 461~1 388 cm~(-1)处和1 174~996 cm~(-1)处分别出现含有部分双键性质的C…N键和C…S键的特征吸收峰;元素分析结果表明该化合物中碳、氢、氮、硫的摩尔比近似为2:4:1:1。在0.5mol/L的硫酸介质中,0.5 mmol/L的DTC-TETA对黄铜管表现出很好的缓蚀效果。
A Sodion Triethylenetetramine-bisDithiocarbamate(DTC-TETA) as a copper corrosion inhibitor in acidic solution was synthesized and its structure was investigated by FTIR and elemental analysis,respectively.The FTIR spectrum of DTC-TETA showed strong absorption peaks at 1 461 ~ 1 388cm~(-1) and 1 174 ~996cm~(-1) which were attributed to partly double bonds of C…N and C…S,respectively.The elemental analysis results demonstrated that the mol ratio of C,H,N,S in DTC-TETA was about 2:4:1:1.DTC-TETA at the concentration of 0.5mmol/L showed good inhibition effect on brass corrosion in 0.5mol(L~(-1) sulphuric acid.
