Abstract

Two diamine based water lean solvents PNH and ENH (N,N-dimethyl-1,3-propanediamine (DMPDA) and N,N-dimethyl-1,2-ethanediamine (DMEDA) respectively) using N-methyl pyrrolidone (NMP) as a diluent together with their corresponding aqueous solvents were investigated for their corrosivity of carbon steel. Siderite (FeCO₃) film is demonstrated to provide stronger corrosion resistance than chukanovite (Fe₂(CO₃)(OH)₂) film formed in aqueous solvents, DMEDA-H₂O and DMPDA-H₂O. Diamine water lean solvents ENH and PNH showed more severe corrosion behavior (ten-fold higher dissolved iron concentration) due to a lack of film protection. Improved anti-corrosion ability was observed in diamine water lean solvents by increasing the water content to 40%.
