Abstract
An increasing demand for lubricants and the awareness of environmental preservation lead the production of lubricant base oils and degradable additives. The widely used corrosion inhibitors are alkaline metal and alkaline earth metal salts of sulphonic acids. One of their weakness is that the metal substance is non degradable. Therefore studies of the production of vegetable oil-based inhibitors containing sulphonic acid are needed. Epoxidized methyl esters that contain sulphonates behave as corrosion inhibitor. The purpose of this research is to analyze the reaction between Epoxidized rice bran oil methyl ester (ERME) and Linear alkylbenzene sulphonic acid (LABSA). The method used was mixing ERME with LABSA for 4 hours, then heating the mixture up to 40°C. The process variable is weight ratio of ERME : LABSA = 1 : 1.1 ; 1 : 1.2 ; 1 : 1.3 and the response variable was oxirane oxygen. The identification was conducted using FTIR (Fourier Transform Infra Red). The equation obtained is y = -43200x + 31,147 with R² = 0,9868, where x is weight ratio of ERME : LABSA and y is oxirane oxygen. The result of this research shows that the best weight ratio of ERME : LABSA 1:1,3 with oxirane oxygen of 0,5%. FTIR test result indicates the presence of hydroxyl groups and sulphonic acids.
