Physicochemical properties (vapor pressure, water solubility, gas-phase nuclear magnetic resonance) of 8-2 Telomer B alcohol, CF3(CF2)(7)CH2CH2OH, were measured. Vapor pressures were measured in the temperature range from (21 to 200) degreesC by three different methods, including a novel method based on gas-phase NMR that requires only milligram quantities of substance. At 21 degreesC, the vapor pressure was 3 Pa; at 201.3 degreesC, the vapor pressure was 101.325 kPa (1 atm). Water solubility was measured at (12, 25, 37, and 60) degreesC in pure water. Solubility ranged from (134 to 318) mug/L.
