摘　　要：合成了具有炔醇基、氨基和季铵结构的系列化合物，并在此基础之上研制出缓蚀剂IMC－80。利用腐蚀失重和电化学方法，对其在CO2饱和盐水和盐酸体系中的缓蚀性能进行研究．研究结果表明，它们在酸性介质、油田污水介质和含有少量H2S和CO2的伴生水介质中具有优良的缓蚀性能．该级蚀剂在中原油田试用，在控制油井及其相关的集油管线腐蚀上，其效果优于美国同类产品CI－203，A series of compounds, with amine and alkynyl-oxygen alkyl groups in the molec-ular structure, were synthesized. Based on the synthesized compounds, a new corrosion in-hibitor IMC-80 was formulated and its per formance was investigated using weight loss andelectrochemical methods in brine saturated with CO2 and hydrochloric acid solution. The re-sults show that the inhibitor has a higher inhibition effeciency in acid medium, oil well,sewage and water soluted a little H2S and CO2. The inhibitor has been used to protect oilwell and its pipeline from corrosion, the inhibition effeciency is more than that of CI-203made in U. S. A.
