Abstract: At present, a large number of studies of biodiesel production process using simulation packages are being developed. In these studies, vegetable oils and biodiesels are characterized in the software through representative compounds because of they are not in the compounds database of commercial simulators. With the aim to achieve a successfully characterization in these kinds of software, some properties of the substances must be available. The normal boiling point (NBP) is the most important property due to the fact that this property along with group contribution methods allows other properties calculation such as, e. g., critical properties and temperature dependency properties. In this work, a thermogravimetric analysis (TGA) method for rapid measurement of normal boiling points of two triacylglycerols and four ethyl esters, i.e., triolein, tripalmitin, ethyl oleate, ethyl palmitate, ethyl linoleate and ethyl ricinoleate, was used. Nowadays, in the open literature exists few data available about ethyl esters properties; hence, the results obtained here will contribute in the proposal, analysis, and evaluation of ethyl esters (biodiesel) virtual plants using reliable simulation packages. In addition, a more accurate characterization of compounds and therefore more accurate simulation results can be obtained when they are used. (C) 2011 Elsevier Ltd. All rights reserved.
