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 conversions >95% 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.
本文报道了以氢氧化钠为催化剂，由精炼脱胶大豆油和蓖麻油生产脂肪酸乙酯的实验数据。研究的变量包括温度（30 - 70摄氏度）、反应时间（1 - 3小时）、催化剂浓度（0.5 - 1.5 w/wt%）以及油与乙醇的摩尔比（1:3 - 1:9）。文中给出了工艺变量对反应转化率的影响以及最佳实验条件。结果表明，所有研究体系的转化率均>95%。总体而言，反应温度、反应时间以及油与乙醇摩尔比的增加会导致反应转化率提高，而催化剂浓度则呈现相反的趋势。
