| dc.description | Anthraquinones (AQs) are an important category of secondary metabolites present in various
vegetable species [1]. They are highly bioactive compounds, potentially useful for therapeutic
applications, as antiviral, anti-bacterial and anti-cancer agents [2-5]. Extraction processes using
pressurized hot water and supercritical fluids offer an environmentally friendly alternative to
traditional extracting and purifying methods applied to anthraquinone-containing plants [6,7] .
Knowledge on high-pressure phase equilibria of AQs + solvent mixtures is required to evaluate
the potentiality of these processes. The need is for both, experimental data and thermodynamic
models that are able to predict phase boundaries at different process conditions. In this work,
the solubility of 1,4-dihydroxy-9,10-anthraquinone (quinizarin) in pressurized hot water have
been measured, using a simple and reliable dynamic method. For the binary quinizarin + H2O,
the measurements covered a range of 333-463 K and pressures closed to 3, 6 and 9 MPa. The
group-contribution with association equation of state GCA-EOS [8] was used to calculate
solid-liquid equilibria of binary mixtures of AQs with pressurized hot water. | |
