2-((4-(dimethylamino) benzylidene)amino)benzenethiol (DBB) compound has been synthesized and tested for prevention of carbon steel corrosion in HCl at different temperatures. The research was carried out using electrochemical and microscopic techniques. Extended tests were conducted at 25 °C while short-term tests were performed at 25 °C and 55 °C. The inhibition efficiency increased with increasing temperature and increasing immersion time. Temperature rise changed the inhibitor's adsorption character. Activation parameters E_a, ΔH_a* and ΔS_a* were evaluated and discussed. Inhibition properties of DBB was investigated by quantum chemical calculation at wB97XD/6-311+G(d) level in water in a bid to predict DBB interaction with metal.

已合成2-（（4-（二甲基氨基）亚苄基）氨基）苯硫醇（DBB）化合物，并进行了测试，以防止碳钢在HCl中于不同温度下腐蚀。该研究是使用电化学和显微技术进行的。扩展测试在25°C下进行，而短期测试则在25°C和55°C下进行。随着温度的升高和浸入时间的增加，抑制效率也随之提高。温度升高改变了抑制剂的吸附特性。激活参数E _a，ΔH _a *和ΔS _a*经过评估和讨论。通过量子化学计算在水中wB97XD / 6-311 + G（d）水平研究了DBB的抑制特性，以预测DBB与金属的相互作用。
