ABSTRACT
The solubilities of 2,2'-bipyridine and 4,4'-dimethyl-2,2'-bipyridine in supercritical carbon dioxide were measured at temperatures from (308 to 323) K and pressures from (8.1 to 25.9) MPa. The measured solubilities were correlated using a semiempirical model and differed from the measured values by between (4.6 and 34.4) %.
