IUPAC-NIST Solubility Database NIST Standard Reference Database 106 Glass Ball as Bullet Solubility System: 1-Bromoheptane with Water Components: (1) Water; H2O; [7732-18-5] NIST Chemistry WebBook for detail (2) 1-Bromoheptane; C7H15Br; [629-04-9] NIST Chemistry WebBook for detail Evaluator: A. L. Horvath, Imperial Chemical Industries Limited, Runcorn, U.K., July 1993. Critical Evaluation: The solubility of 1-bromoheptane (1) in water (2) has been studied by two work groups in the same laboratory; whereas, the solubility of water (2) in 1-bromoheptane (1) has not been investigated yet. The two experimental investigations by Tewari et al.1 in 1982 and by Miller et al.2 in 1985 are in excellent agreement with respect to the errors estimated by the authors. It is not possible to establish any shortcomings of the experimental procedures from the description. The measurements seem to be performed with care and the method, which involved a modified generator column procedure, gives relatively accurate results. Upon consideration of saturation equilibrium, the method of analysis, and the reported standard deviation, one may conclude the solubility value is quite satisfactory. There are not enough data to allow a more rigorous evaluation to be made; therefore, the solubility value reported here must be tentative. The following solubility of 1-bromoheptane (1) in water (2) given in Table 36 in weight percent, mole fraction, and mole per liter of water is tentative and based primarily on the reported values of Tewari et al.1 and of Miller et al.2 at 298.15 K.
