The solubility of 1-octene in water was reported to be 1.979 × 104 mol L1 at 25°C.a Assuming a solution density of 1.00 g mL1 the corresponding mass percent and mole fraction (x1) solubilities calculated by the compilers are respectively, 0.00222 g(1)/100 g sln and 3.63 x 106. Solubility data are also presented as a function of temperature in various salt solutions.
