| Abstract: | N,N-dihydroxyethyl-(5-methyl-1,3,4]thiadiazol-2-sulfur-)-carbonyl acetamide was syn-thesized by two steps of 5-methyl-2-mercapto-1 ,3 ,4-thiadiazole with diethanolamine and malonic acid . The structure was confirmed by 1 H NMR and IR.Corrosion resistance was investigated by electrochem-ical techniques .The results indicated that when the inhibitor concentration reaches 40 μg· mL-1 , the corrosion potential minimum was -0.505 V, and the corrosion current density minimum was 0.81μA· cm-2 at 25℃in 1.0 mol· L-1 hydrochloric acid solution of test mix of stainless steel and stain-less steel/inhibitor. |
