Facile synthesis of stearoyl diethanolamide and its excellent corrosion-inhibiting properties for carbon steel protection
A facile approach for preparing stearoyl diethanolamide was reported.The as-synthesized product was further applied for the protection of carbon steel from corrosion solution.On the basis of orthogonal experiments,optimal reaction conditions were investigated.The results show that the yield rate can be up to 84.6% under a condition of molar ratio of stearic acid to ethylenediamine is 1 ∶ 1.7,the reaction time and temperature are 4 h and 175 ℃,respectively.The optimal concentration and potential corrosion-inhibiting mechanism were also investigated by using scanning electronic microscopy,weight loss and electrochemical analysis.The presented synthesis route is facile which enable it to be promisingly applied for production widely.Furthermore,the excellent corrosion-inhibiting properties of stearoyl diethanolamide also indicate that it can be a fascinating candidate for protecting steels from corrosion in oil exploration and transportation.
