Isothermal vapor-liquid equilibria for 21 fluorocarbon + alcohol systems ranging from 283 to 313 K at atmospheric pressure were measured. The solubility of fluorocarbons into alcohols decreases with increase in temperature and is on the order of a thousand times greater than that of water. The solubility of fluorocarbons derived from ethane in methanol increases as the number of hydrogen atoms in a molecule increases. From the experimental data, Henry's law constants of dichlorodifluoromethane (CCl 2 F 2 , CFC12), chlorodifluoromethane (CHClF 2 , HCFC22), difluoromethane (CH 2 F 2 , HFC32), chloropentafluoroethane (C 2 ClF 5 , CFC115), pentafluoroethane (C 2 HF 5 , HFC125), 1,1,1,2-tetrafluoroethane (CH 2 FCF 3 , HFC134a), and 1,1-difluoroethane (CH 3 CHF 2 , HFC152a) in methanol, ethanol, and 2-propanol were obtained. The values were correlated as a function of temperature with the Valentiner equation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
