本研究对酯交换反应副产物粗甘油的提纯进行了研究。粗甘油的第一步纯化采用中和法，然后用0.45μm滤膜微滤。通过高效液相色谱分析可以仅检测到甘油峰，这表明中和步骤能够从粗甘油样品中除去过量的均相催化剂以及未反应的游离脂肪酸。然而，然后通过使用两种类型的Amberlite树脂的离子交换过程消除来自盐和催化剂的游离离子，以产生高达99.4%的更高的甘油纯度。甘油的纯度通过其他分析如傅立叶变换红外、美国药典和美国测试与材料协会方法来确认。采用Super-Pro-Designer7.0软件进行模拟研究，该软件可为工业规模提供数据。P2和P5模拟过程给出了98.35重量%的更高纯度的纯甘油。%和99.27wt%。实验和模拟过程的结合为今后工业规模的实验室实验投入研究提供了一条很好的途径。
In this study, the purification of crude glycerol as a by-product of transesterification reaction was investigated. The first purification stage of the crude glycerol was achieved by employing the neutralization method, followed by microfiltration using 0.45μm filter membrane. Only glycerol peak could be detected by high performance liquid chromatography analysis which indicating that the neutralization step enabled to removal of excess homogeneous catalyst as well as the unreacted free fatty acids from crude glycerol samples. However, the free ions from salt and catalyst were then eliminated through an ion exchange process using two types of Amberlite resins to produce higher glycerol purity up to 99.4%. The purity of glycerol was confirmed by the other analysis such as the Fourier transform infrared, United States Pharmacopoeia and American society for testing and materials methods. The simulation studies were applied using Super-Pro-Designer 7.0 software which can provide the data for scale up to industrial scale. The P2 and P5 simulation process gives a higher purity of pure glycerol of 98.35 wt. % and 99.27 wt%, respectively were generated after through several combinatorial purification steps. The combination between the experimental and simulation process showed a good way to investigate the laboratory experiment input for possible industry scale in future.
