| 摘 要： | 合成了2种癸二酸咪唑啉季铵盐癸二酸-水杨酸咪唑啉季铵盐(SSAI)和癸二酸咪唑啉季铵盐(SAI)，并采用失重法和电化学方法研究了这2种咪唑啉季铵盐对N80钢在1 mol/L HCl溶液中的缓蚀性能和吸附行为。 结果表明，在1 mol/L HCl溶液中这2种化合物对N80钢均有较好的缓蚀作用，缓蚀效率大小顺序为SSAI＞SAI。 SSAI和SAI均为混合偏阳极型缓蚀剂。 2种化合物在N80钢表面的吸附服从Langmuir吸附等温式，属于化学吸附。

| Abstract: | Two sebacic acid imidazoline quaternary ammonium salts,sebacic acid-salicylic acid imidazoline quaternary ammonium salts(SSAI) and sebacic acid imidazoline quaternary ammonium salts(SAI),were synthesized and their inhibition action and adsorption behavior on N80 steel in 1 mol/L hydrochloric solution were investigated by means of mass loss and electrochemical techniques.It was showed that the two compounds had good corrosion inhibition for N80 steel in 1 mol/L HCl solution.SSAI was found to have a superior inhibition efficiency to SAI.Both SSAI and SAI were mixed-type inhibitors and mainly inhibited anode process against N80 steel in 1 mol/L HCl solution.The experimental results revealed that the adsorption processes were exothermic reaction and belong to chemical adsorption. |
