Abstract Normal boiling point is an important thermophysical property for quality control of biofuels, as biodiesel, and is related to purification processes as distillation. Monoacylglycerols and diacylglycerols are formed during transesterification reaction of oils, and directly affect quality parameters of biodiesel, as its viscosity. Nevertheless, to the best of our knowledge, normal boiling point data of partial acylglycerols are completely absent in the open literature. This paper goals at providing experimental data of normal boiling points for five monoacylglycerols, monobutyrin, monocaprin, monolaurin, monopalmitin and monoestearin, and three diacylglycerols, dicaprylin, dinonanoin and dicaprin using the thermogravimetric analysis (TGA) technique. Predictive capacities of available methods in the literature were also evaluated.

偏酰基甘油标准沸点的实验数据及预测

摘要 正常沸点是生物燃料（如生物柴油）质量控制的重要热物理特性，与蒸馏等纯化过程有关。单酰基甘油和二酰基甘油在油的酯交换反应过程中形成，直接影响生物柴油的质量参数，如其粘度。然而，据我们所知，部分酰基甘油的正常沸点数据在公开文献中完全不存在。本文旨在使用热重分析 (TGA) 技术提供五种单酰基甘油（单丁酸甘油酯、单癸酸甘油酯、单月桂酸甘油酯、单棕榈酸甘油酯和单硬脂酸甘油酯）和三种二酰基甘油（双辛酸、二壬酸和双癸酸）的正常沸点实验数据。还评估了文献中可用方法的预测能力。
