Abstract
The solubility of isomeric o-, m- and p-coumaric acids in supercritical carbon dioxide were measured by a flow-type experimental apparatus at 308.15-323.15 K and 8.5-25 MPa. The data were modeled by an empirical density-based correlation and a recent EOS formulated by the authors based on approximated lattice-hole theory. We found that m-coumaric acid showed the highest solubility and o-coumaric acid showed the lowest solubility at the experimental pressures and temperatures.
