3-4-2　アシルグリセロールの固化挙動がバイオディーゼルの低温流動性に与える影響

抄録

Acylglycerols, such as monoacylglycerol (MAG), diacylglycerol (DAG), and triacylglycerol (TAG), are minor components in biodiesel (fatty acid methyl ester, FAME). Because high melting points and the polymorphic nature of acylglycerols affect the cold flow properties of biodiesel, their solidification behavior was investigated in this study. The liquidus temperatures of binary mixtures of FAME, MAG, DAG, and TAG were determined by differential scanning calorimetry. The results were compared with estimates from three thermodynamic prediction models: ideal solution (IS), non-ideal solution (NIS), and compound formation (CF) models. The role of each acylglycerol species in the development of prediction models for the cold flow properties was discussed.
