在运输及仓储过程中 ,使用气相缓蚀剂是防止大气腐蚀最有效的方法。为了开发研制适用于多种金属的气相缓蚀剂 ,我们合成了五种氨基苯并噻唑衍生物 ,并且在相对湿度为 10 0 %的条件下采用失重法和电位极化法研究了这些化合物对低碳钢、紫铜和黄铜的腐蚀抑制作用。在所有被研究的化合物中 ,6羟甲基氨基苯并噻唑肉桂酸盐以其 90 %的缓蚀率 ,而表现出最佳的缓蚀效果。所有这些缓蚀剂对金属的腐蚀电位都显著地向基线方向发生位移 ,这表明它们主要为阳极型缓蚀剂。
In the transport and storage process, the use of vapor corrosion inhibitor is the most effective way to prevent atmospheric corrosion. In order to develop a vapor-phase corrosion inhibitor suitable for a variety of metals, we synthesized five derivatives of aminobenzothiazole and studied the effect of these compounds on the condition of relative humidity of 10% by weight loss and potential polarization Corrosion inhibition of mild steel, copper and brass. Of all the compounds studied, 6-hydroxymethylaminobenzothiazole cinnamate showed the best corrosion inhibition with its 90% inhibition rate. The corrosion potentials of all these corrosion inhibitors on metals are significantly shifted toward the baseline, indicating that they are predominantly anodic corrosion inhibitors.
