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 {times} 10{sup {minus}4} and 6.3 {times} 10{sup {minus}3} for H{sub 2} in methanol and between 7 {times} 10{sup {minus}4} and 6.9 {times} 10{sup {minus}3} for H{sub 2} in methyl formate. The Henry`s law constants were about 620 MPa for H{sub 2} in methanol and 630 MPa for H{sub 2} 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. The application is to the two-stage liquid phase methanol synthesis process which starts with carbonylation of methanol to methyl formate, then followed by hydrogenolysis of the formate, to recover wasted or unused discharged heat from industrial sources for the thermal energy demands.
