Description
Summary:The esterification of oleic acid and methanol using sulfuric acid as a homogeneous catalyst is studied in reactive‐separation systems. The conversion of the free fatty acid was investigated in two different experiments with the molar ratio of methanol/oleic acid, amount of catalyst, temperature, and reaction time as variables. The conversion of the free fatty acid was found to depend strongly on the molar ratio of methanol/oleic acid. The reaction time had a direct effect on the conversion of the free fatty acid, and this conversion decreased with higher temperature. These results were valuable for a preliminary study on biodiesel production, using an acid homogeneous catalyst in a reactive dividing‐wall distillation column. Esterification of oleic acid with methanol taking H2SO4 as catalyst was investigated in a batch reactive‐separation system. The results were applied for scaling up the process to an experimental reactive dividing‐wall distillation column, where a preliminary experimental study was carried out in order to corroborate the production of methyl oleate.
