Solubility and Partial Molar Volume of Bipyridine Derivatives in Supercritical CO2
摘要
Abstract
The solubilities of bis(2-(2-butoxyethoxy)ethyl)-2,2′-bipyridine-4,4′-dicarboxylate, bis(2-(2-ethoxyethoxy) ethyl)-2,2′-bipyridine-4,4′-dicarboxylate, and bis(2-butoxyethyl)-2,2′-bipyridine-4,4′-dicarboxylate in supercritical CO2 were measured by fixed volume visualization method at different temperatures (313K, 323K, 333K) and pressures (10.4~18.8 MPa).The data were correlated by Bartle and Chrastil semiempirical model and showed good correlations .The AARD in Bartle and Chrastil semiempirical model for the 3 bipyridine derivatives were 10.71%, 16.20%, 4.96% and 8.31%, 11.36%, 5.36%respectively.The partial molar volumes calculated by Kumar-Johnston theory were in the range of -14711.5 to -1629.9 cm3/mol.关键词
