Biodiesel is a very promising renewable energy, whose properties are determined by fatty acid esters in it. The work aims to develop prediction models based on their mol. structure to estimate the d. and viscosity of saturated and unsaturated fatty acid esters in a wide range of temperature and pressure. Densities and viscosities of Et hexanoate and Et nonanoate were measured from 313.15 K to 363.15 K and at pressures up to 15 MPa to get more exptl. data. The effect of temperature, pressure and mol. structure on d. and viscosity based on the exptl. data in this work and collected from literature found an interesting phenomenon that densities decrease with the increasing carbon atoms number in the chain of the saturated fatty acid esters at low temperature, but there is an opposite trend at high temperature Two models derived from the Tait equation were proposed for densities with the average absolute relative deviation of 0.15% for saturated fatty acid Me esters (FAMEs), 0.13% for saturates fatty acid Et esters (FAEEs), 0.17% for unsaturated FAMEs, 0.06% for unsaturated FAEEs, resp. For viscosity, two models based on the Andrade-Tait model were proposed with the average absolute relative deviation of 1.49% for saturated FAMEs, 0.92% for saturated FAEEs, 4.54% for unsaturated FAMEs and 2.15% for unsaturated FAEEs, resp.
Journal of Molecular Liquids published new progress about Density. 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Application of Ethyl nonanoate.
