Additional information

McAuliffe (1966) is well documented and meets basic scientific principles. The solubilities of 65 hydrocarbons in water were measured, at room temperature, by the direct injection of hydrocarbon-saturated water into a gas chromatograph. The concentration of hydrocarbon was determined by measuring the area under the chromatogram peak. It is unclear what effect impurities might have had on the result and how the authors accounted for them in determining the solubility value. The study predates implementation of GLP and development of standard guidelines but otherwise acceptable for assessment and has been classified as reliable with restrictions.
