Abstract
The effect of phosphonium—based ionic liquids (ILs): 1,3-dimethyl-imidazolium dimethyl phosphate, [C1C1IM][DMP], 1-ethyl-1-methylpyrrolidinium dimethyl phosphate, [C1C2PYR][DMP], 1-hydroxyethyl-1-methylpyrrolidinium dimethyl phosphate, [C1C2OHPYR][DMP], 1-methylpyridinium dimethyl phosphate, [C1Py][DMP], 1-ethyl-1-methylmorpholinium dimethyl phosphate, [C1C2MOR][DMP], 1-ethyl-1-methylpiperidinium dimethyl phosphate, [C1C2PIP][DMP], N,N,N-trimethyl-N-methylammonium dimethyl phosphate, [N1,2,2,2][DMP], 1-ethyl-3-methylimidazolium diethyl phosphate, [C1C2IM][DEP], 1-ethyl-1-methylpyrrolidinium diethyl phosphate, [C1C2PYR][DEP], 1-ethyl-1-methyl-morpholinium diethyl phosphate, [C1C2MOR][DEP] and tri(butyl)ethylphosphonium diethyl phosphate, [P2,4,4,4][DEP] on the corrosion of aluminium and copper were investigated using potentiodynamic polarization. All tested ionic liquids formed a passivation layer on the surface of the tested metals and due to their low affinity to promote corrosion of Cu and Al, can be used in refrigeration technology.
期刊介绍:
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
