Gas-liquid solubility of hydrogen in n-alcohols (1≤n≤4) at pressures from 3.6 MPa to 10 MPa and temperatures from 298.15 K to 525.15 K

The gas-liquid solubility of hydrogen in methanol, ethanol, 1-propanol, and 1-butanol at pressures in the range 3.6 to 10 MPa and at temperatures in the range 298.15 to 525.15 K has been measured in an autoclave type phase equilibrium apparatus using the total pressure method. Pseudo-Henry's law constants, H-2,1(PS), were calculated. The solubility of hydrogen increases with increasing temperature and pressure for all solvents used, and it also increases as the carbon chain length of the alcohol molecule increases.
