研究了BTA，MBI，MBT等3种铜缓蚀剂在H2S环境中的缓蚀性能，采用量子化学研究方法对实验结果进行了分析，研究了苯三唑在铜表面所形成的配合物保护膜的稳定性。结果表明，MBT抗H2S腐蚀性能较差，BTA是铜及其合金在H2S环境中理想的接触缓蚀剂和气相缓蚀剂。
研究瞭BTA，MBI，MBT等3種銅緩蝕劑在H2S環境中的緩蝕性能，採用量子化學研究方法對實驗結果進行瞭分析，研究瞭苯三唑在銅錶麵所形成的配閤物保護膜的穩定性。結果錶明，MBT抗H2S腐蝕性能較差，BTA是銅及其閤金在H2S環境中理想的接觸緩蝕劑和氣相緩蝕劑。

The existence of H2S in environment is one of the factors causing discoloration of Cu. The inhibition of BTA, MBI, MBT, and the stability of BTA -Cu protection layer in H2S atmosphere were investigated. The experimental results were analyzed by quantum chemistry calculation method. Results indicated that BTA is a perfect corrosion inhibitor for Cu in H2S environment while the performance of MBT is discontented.
