The ionic liquid 1-butyl-3-methylimidazolium tetrachloroferrate (Bmim [FeCI4] have received vast attention recently, due to its versatility and broad usage in petrochemical industry. Several researches have been carried out to study the importance of Bmim [FeCI4] in the industrial application and it plays important roles in many sector of the industry as in desulfurization of crude oil and synthesizing polymer (C.X. Wang, 2010). However, there is no paper report on the hazard of Bmim [FeC4]. Thus, this project is designed to develop the corrosion rate of Bmim [FeCI4] towards A36 mild steel. The characteristic of the steel is studied to determine the composition of the steel which is crucial in the study of corrosion process. The A36 mild steel is widely used in the petrochemical industry as the raw material in piping and storage tank (L. Brockenbrough, 1994). Therefore, the study of corrosion of ionic liquid Bmim [FeC14] towards mild steel is very crucial. The rate of corrosion, mm/year is examined in this project. The main methods used to determine the corrosion rate is immersion test and Electrochemical Corrosion Measurement Techniques. The parameters of water content and temperature effect are studied in this project. The polarization technique is applied on both parameters and Tafel plot, Potentiodynamic and Linear Polarization Resistance (LPR) is designed. The technique and procedure highlighted in this project is based on several journals and reference books.
