Fatty acids (FAs) are important as raw materials for the biotechnology industry. Existing methods of FAs production are based on chemical methods. In this study potassium hydroxide (KOH)-catalyzed reactions were utilized to hydrolysis Jatropha curcas seed oil.
The parameters effect of ethanolic KOH concentration, reaction temperature, and reaction time to free fatty acid (FFA%) were investigated using D-Optimal Design. Characterization of the product has been studied using Fourier transforms infrared spectroscopy (FTIR), gas chromatography (GC) and high performance liquid chromatography (HPLC). The optimum conditions for maximum FFA% were achieved at 1.75M of ethanolic KOH concentration, 65°C of reaction temperature and 2.0 h of reaction time.
This study showed that ethanolic KOH concentration was significant variable for J. curcas seed oil hydrolysis. In a 18-point experimental design, FFA% of hydrolyzed J. curcas seed oil can be raised from 1.89% to 102.2%, which proved by FTIR and HPLC.
脂肪酸(FAs)作为生物技术产业的原材料至关重要。现有的脂肪酸生产方法基于化学方法。在本研究中,利用氢氧化钾(KOH)催化反应水解麻疯树籽油。
采用D - 最优设计研究了乙醇氢氧化钾浓度、反应温度和反应时间对游离脂肪酸(FFA%)的参数影响。使用傅里叶变换红外光谱(FTIR)、气相色谱(GC)和高效液相色谱(HPLC)对产物进行了表征。在乙醇氢氧化钾浓度为1.75M、反应温度为65°C和反应时间为2.0小时的条件下实现了最大FFA%的最佳条件。
本研究表明乙醇氢氧化钾浓度是麻疯树籽油水解的显著变量。在18点实验设计中,经FTIR和HPLC证明,水解麻疯树籽油的FFA%可从1.89%提高到102.2%。
