The solubilities of a variety of substituted phenols and benzoic acid derivatives is determined in supercritical difluoromethane (HFC-32) at 90 degreesC using a capacitative method, and they are presented as a function of pressure. The compounds are shown to be more soluble than they are in CO2 under comparative conditions. The enhancement factor is used as a way of expressing solubility to remove the effect of vapor pressure; the observed trend is explained in terms of the polarity of the substituents. The solubility data are fitted to a Peng-Robinson equation of state for which a good correlation is observed.
