Isothermal hydrogen solubility in methanol has been measured at six temperatures: 248.41, 263.38, 278.01, 278.25, 291.20 and 308.20K up to 3.4MPa. Hydrogen solubility has been found an increasing function of temperature in the range of studied temperatures. The apparatus used in this work can be operated either as a static analytic technique with a on line gas chromatograph or as a synthetic one. The static analytic method takes advantage of a movable pneumatic capillary sampler (Rolsi, Armines patent). The apparatus was used following a synthetic mode at 278.25K from 0.04 to 0.33MPa in order to compare the data obtained through the two techniques. The data are congruent. A comparison analysis is performed with measurements from Bezanehtak et al. [K. Bezanehtak, G.B. Combes, F. Dehghani, N.R. Foster, J. Chem. Eng. Data, 47 (2002) 161 168], Wainwright et al. [M.S. Wainwright, T. Ahn, D.L. Trimm, N.W. Cant, J. Chem. Eng. Data, 32 (1987) 22 24], Yorizane et al. [M. Yorizane, S. Sadamoto, H. Masuoka, Y. Eto, Kogyo Kagaku Zasshi, 72 (1969) 2174 2177] and Liu et al. [Q. Liu, F. Takemura, A. Yabe, J. Chem. Eng. Data, 41 (1996) 1141 1143]. The Henry s law constants were calculated, and a temperature dependent empirical correlation has been produced, based on experimental data.
