摘　　要：合成了四种苯骈三氮唑 (BTA)的酰基衍生物。并采用失重法、电化学法和表面分析法研究了它们在 3 %NaCl溶液中对铜的缓蚀作用。结果表明 :BTA的四种酰基衍生物的缓蚀性能均优于BTA 。Four types of carbonyl derivatives of benzotriazole (BTA) were synthesized. Their inhibition effects for copper corrosion in 3% NaCl solution were investigated by weight-loss, electrochemical method and surface analysis. The results showed that the four types of BTA derivatives exhibited better protection compared with BTA under the same experimental conditions. Among them, the most effective corrosion inhibitor is X 4-BTA.
