采用表面张力测定法、腐蚀速率快速评定仪法、极化曲线法和交流阻抗曲线法，研究了在高氯离子的水溶液和减三油经催化裂化后的产品油溶液形成的混合液中二乙基二硫代氨基甲酸钠对 A106B钢的缓蚀行为，并采用扫描电镜法分析缓蚀前后碳钢表面形貌。结果表明，在油水混合液中 SDDTC在质量浓度为0.75 g/L时具有最佳缓蚀效果，缓蚀效率大于85%；与不同质量浓度丙炔醇复配后均比单独使用 SDDTC效果更好，丙炔醇质量浓度为0.2 g/L时效果最佳，缓蚀效率大于95%。

The effect of inhibitors on A106B steel in the mixture of high chloride solution an d oil product solution after catalytic cracking was studied by surface tension,corrosion rate assessment instrument,polarization curves and EIS.The surface morphology of carbon steel was analyzed by SEM.The experiments showed that in the solution of oil-water mixture, SDDTC with concentration of 0.75 g/L had the best inhibiton effect,which inhibition efficiency reached 85%.However, synergy with different concentations of propargyl alcohol has a better effect than using SDDTC alone.When propargyl alcohol concentration was 0.2 g/L,the inhibition efficiency was more than 95%.
