Two imidazole derivatives, 2‐(2‐((benzo[d]thiazol‐2‐ylthio)methyl)‐4,5‐dihydro‐1H‐imidazol‐1‐yl)ethan‐1‐ol (BTM) and 2‐(2‐((1H‐benzo[d][1,2,3]triazol‐1‐yl)methyl)‐4,5‐dihydro‐1H‐imidazol‐1‐yl)ethan‐1‐ol (BTMS), as a new corrosion inhibitor were synthesized, and their inhibition behaviors for mild steel contained in emulsion were investigated by gravimetric experiment, electrochemical tests, and theoretical calculations. The results show that the inhibition effect of BTMS is better than that of BTM, the maximum value of the inhibition efficiency reaches 97.9%. The resultant adsorption films from BTM/BTMS adsorbed on mild steel, effectively inhibiting the corrosion of mild steel is mainly through chemisorption and follow to Langmuir's adsorption isotherm.

新型缓蚀剂咪唑衍生物在水包油乳液中对低碳钢的腐蚀行为研究

两种咪唑衍生物，2-（2-（（（苯并[ d ]噻唑-2-基硫基]甲基]甲基] -4,5-二氢-1H-咪唑-1-基）乙-1-醇（BTM）和2- （2 - （（1 ħ -苯并[ d ] [1,2,3]三唑-1-基）甲基）-4,5-二氢- 1 ħ合成了一种新型的缓蚀剂-咪唑-1-基）乙-1-醇（BTMS），并通过重量分析，电化学测试和理论计算研究了它们对乳状液中低碳钢的缓蚀性能。结果表明，BTMS的抑菌效果优于BTM，抑菌效率的最大值达到97.9％。BTM / BTMS产生的吸附膜吸附在低碳钢上，主要通过化学吸附作用，有效地抑制了低碳钢的腐蚀，并遵循Langmuir的吸附等温线。
