摘要

Three products are synthesized by adjusting current density and quantity of ionic liquid [Bmim][PF 6 ]in electrochemical oxidation of piperazine. The molecular structures of N-methoxyl piperazine, N-carbonyl piperazine and N, N’-dicarbonyl piperazine are determined by infrared spectroscopy and gaschromatography (GC)/mass spectrometry (MS). For application, the inhibition effect of the threeproducts on the corrosion of HP13Cr steel in 20% (weight %) HCl solution was studied by means ofweight loss and polarization measurements. The experiments revealed that N-carbonyl piperazine andN, N’-dicarbonyl piperazine show 91.0% and 95.2% inhibition efficiencies respectively at theconcentration of 3% (weight %). However, the product of N-methoxyl piperazine has no inhibitionbehavior.
