| Popis: | This article reports experimental data on the production of fatty acid ethyl esters from refined and degummed soybean oil and castor oil using NaOH as catalyst. The variables investigated were temperature (30-70 degrees C), reaction time (1-3 h), catalyst concentration (0.5-1.5 w/wt%), and oil-to-ethanol molar ratio (1:3-1:9). The effects of process variables on the reaction conversion as well as the optimum experimental conditions are presented. The results show that conversions95% were achieved for all systems investigated. In general, an increase in reaction temperature, reaction time, and in oil-to-ethanol molar ratio led to an enhancement in reaction conversion, whereas an opposite trend was verified with respect to catalyst concentration. |
