摘要：
The extraction of fatty acids and their derivatives from sea buckthorn seeds with supercritical carbon dioxide is experimentally studied. A theoretical model of supercritical extraction of organic oil is constructed. The thermodynamics of dissolution of high-molecular-weight substances under supercritical conditions is described in terms of the Redlich-Kwong equation of state. The diffusion of macromolecules of substances contained in organic oil in seed pores is described using a model of a contractin,(, core. The calculated results are compared to experimental data. The pseudocritical parameters of organic oil and its saturation vapor pressure are estimated.
