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,, 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.
