最近合成的化合物1(苄基)1-H-4，5-二苯甲酰基-1，2，3-三唑(BDBT)具有相当多的芳香族体系。三唑环的三个氮原子上有相当数量的电子可用。研究了BDBT对低碳钢在酸性介质中的缓蚀作用。采用塔菲尔极化技术、交流阻抗测量和连续线性极化电阻法，并与旋转圆柱体电极装置相结合。加入50ppm的BDBT，可使低碳钢在1%HCl中的腐蚀速率降低95%以上。BDBT具有混合缓蚀作用，其自由腐蚀电位明显向阴极方向移动。膜持久性测试表明，BDBT在电极表面形成了一层稳定的膜。版权所有(C)1996爱思唯尔科学有限公司
The recently synthesized compound 1(benzyl)1-H-4,5-dibenzoyl-1,2,3-triazole (BDBT) possesses a considerable number of aromatic systems. A significant number of electrons are available on the three nitrogen atoms of the triazole ring. The inhibition effect of BDBT on the corrosion activity of mild steel in acid media has been investigated. Tafel polarization technique, AC impedance measurements and continuous linear polarization resistance method were employed in conjunction with a rotating cylinder electrode apparatus. The corrosion rate of mild steel in 1% HCl was reduced by more than 95% in the presence of 50 ppm of BDBT. The BDBT has a mixed inhibition effect with a significant shift in the free corrosion potential to the cathodic direction. Film persistency tests showed that BDBT forms a stable film on the surface of the electrode. Copyright (C) 1996 Elsevier Science Ltd
