Gas-Liquid Solubility of Hydrogen in n-Alcohols (1<=n<=4)at Pressures from 3.6MPa to 10 MPa and Temperatures from 298.15K to 525.15K

摘要

The gas-liquid solubility of hydrogen in methanol, ethanol, 1-propanol, and 1-butanol at pressures in t he 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 appraratus 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.
