Abstract:	The central task of this research is devoted to the measurement of the solubility of two antioxidants-D-isoascorbic acid and calcium L-ascorbate dihydrate-in supercritical carbon dioxide. The experiment, using a semiflow type apparatus, takes data at various temperatures, over pressures ranging from 12 MPa to 24 MPa. The acquired data are then processed numerically-with the aid of semiempirical equations proposed by Chrastil and by Mendez-Santiago and Teja-to find the correlated relationship. The correlated results from both equations yield satisfactory results with an average absolute relative deviation (AARD) under 5 % when optimally fitted parameters are chosen.
