Abstract

The solubilities of hydrogen gas in liquid phase methanol and methyl formate were measured under pressures up to 1500 kPa and temperatures to 140 °C. The mole fraction solubilities were between 7.9 × 10-4 and 6.3 × 10-3 for H2 in methanol and between 7 × 10-4 and 6.9 × 10-3 for H2 in methyl formate. The Henry's law constants were about 620 MPa for H2 in methanol and 630 MPa for H2 in methyl formate at a temperature of 20 °C. The Henry's law constants show a decrease with increase of temperature. Empirical correlations for solubilities at various temperatures were given on the basis of the experimental data.
