Methyl Oleat Synthesis Using H2SO4 Catalysts And Homogeneous Dispersing Devices At Room Temperature
Introduction
Methyl oleat synthesis is a crucial process in the production of biodiesel and other industrial applications. The esterification of oleic acid with methanol using H2SO4 as a catalyst and a homogeneous dispersing device at room temperature is a promising method for achieving high conversion efficiency. This study focuses on optimizing three important parameters: oleic acid molar ratio to methanol, catalyst concentration, and rotation speed to achieve the optimal reaction condition.
Experimental Methodology
The synthesis of methyl oleat was carried out using the esterification of oleic acid with methanol in the presence of H2SO4 as a catalyst and a homogeneous dispersing device at room temperature. The reaction conditions were varied to study the effect of oleic acid molar ratio to methanol, catalyst concentration, and rotation speed on the conversion of methyl oleat.
Optimization of Reaction Conditions
The reaction conditions were optimized by varying the oleic acid molar ratio to methanol, catalyst concentration, and rotation speed. The results showed that the optimal reaction condition was achieved at an oleic acid molar ratio to methanol of 1:12, a catalyst concentration of 0.7 M, a rotation speed of 4000 rpm, and a reaction time of 60 minutes.
Effect of Oleic Acid Molar Ratio to Methanol
The effect of oleic acid molar ratio to methanol on the conversion of methyl oleat was studied by varying the ratio from 1:6 to 1:12. The results showed that a higher molar ratio of methanol to oleic acid resulted in increased productivity and conversion efficiency.
Effect of Catalyst Concentration
The effect of catalyst concentration on the conversion of methyl oleat was studied by varying the concentration of H2SO4 from 0.1 M to 0.7 M. The results showed that a higher catalyst concentration resulted in increased conversion efficiency and productivity.
Effect of Rotation Speed
The effect of rotation speed on the conversion of methyl oleat was studied by varying the rotation speed of the homogeneous dispersing device from 3000 rpm to 5000 rpm. The results showed that a higher rotation speed resulted in increased homogeneity of the reaction mixture and improved conversion efficiency.
Characterization of Methyl Oleat
The characterization of methyl oleat was carried out using FT-IR and gas chromatography analysis. The results showed that the synthesized methyl oleat had a high conversion efficiency of 96.9 ± 0.1%, supported by the results of gas chromatography analysis which showed a figure of 97.2%. The analysis with the FT-IR spectrophotometer showed the presence of the ester in the wave number 1738.8 cm-1, and the vibration of the -OH carboxylic acid stretches was not detected in the area of 3400-2400 cm-1.
Conclusion
The synthesis of methyl oleat using H2SO4 as a catalyst and a homogeneous dispersing device at room temperature is a promising method for achieving high conversion efficiency. The optimization of reaction conditions, including oleic acid molar ratio to methanol, catalyst concentration, and rotation speed, resulted in the achievement of optimal results.
