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.
