Abstract

Epoxide is needed and used in the production of polyurethane, poly vinyl chloride, lubricants, and chemicals because of the high reactivity of the oxirane ring. Epoxidized methyl ester can be used to improve the rheology of base oils applied as surfactants and additives to numerous industrial products. Its reaction with a sulphonic acid group, such as the linear alkylbenzene sulphonate (LAS) or linear alkylbenzene sulphonic acid (LABSA) improves the oxidation stability and inhibits the corrosion caused by vegetable and mineral oils as base lubricants. The aim of this research is to study the effect of temperature on oxirane oxygen in the uncatalyzed reaction of epoxidized methyl oleic (EMO) of rice bran oil with LABSA and to identify the reaction product by using FTIR, NMR and GC-MS. The correlation between the temperature (y) and the oxirane oxygen (x) is y = -0,0095x + 0,7914 with R² = 0,9452 at EMO : LABSA ratio (w/w) of 1:1,3. The presence of a peak in the product FTIR spectrum at 3403.844 cm-1 is attributed to a hydroxyl (O-H) group, while that in the range of 1335 cm−1 - 1410 cm−1 – to a sulfonate ester (SO2 –O–) group. The NMR and GC-MS spectra indicate the presence of a hydroxy sulfonic acid ester. These results indicate that the epoxy group may be not completely opened by LABSA
