“…The search for alternative sources of energy has become quite intense, and the reasons can be related to the unwanted oscillations in oil price, the supposed future shortage of fossil fuels, and some well-known environmental concerns related to this nonrenewable commodity . One rather promising source is biodiesel from vegetable oils or animal fat, which constitutes a viable fuel, especially for transportation purposes. Moreover, biodiesel is a source of renewable energy that opens up the possibility of reducing greenhouse-gas emissions relative to fossil fuels .…”

“…This information will be useful in the design of the purification stage, where the hot-water washing step can provide a low ethanol concentration in the biodiesel phase. Although many authors have produced LLE data for systems involving fatty acids, short chain alcohols, water and the corresponding esters [6][7][8][9][10][11][12][13]15,[23][24][25][27][28][29][30][31][32], our study presents a new set of experimental data regarding LLE obtained for mixtures containing fatty acids from soybean soapstock acid oil (FA-SSAO) and their corresponding esters (EE-SSAO). The experimental and theoretical thermodynamic data that we have obtained regarding mutual solubility and phase behavior of the reactants and products of the esterification reaction can be used in the modeling and optimization of a low-temperature enzyme-catalyzed esterification process.…”

“…Although various authors have obtained LLE data for systems related to biodiesel production [6][7][8][9][10][11][12][13], none of them have used a low-cost feedstock, such as fatty acids from soybean soapstock acid oil (FA-SSAO). The aim of the current work was therefore to provide LLE data for components involved in biodiesel production through esterification of FA-SSAO.…”

“…A Figura 3, construída a partir dos dados das frações mássicas experimentais e com os dados correlacionados através do modelo UNIQUAC, apresenta boa correlação dos dados experimentais e calculados. A exemplo dos trabalhos de MESQUITA et al (2012), MAZUTTI et al (2013), PINHEIRO et al (2014), o modelo UNIQUAC obteve uma boa correlação com os dados experimentais. É importante salientar que todos os trabalhos citados anteriormente foram realizados com biodiesel provenientes de diferentes oleaginosas, assim, o modelo pode ser aplicado para diversos sistemas.…”
