✦ Synopsis

Solubility data for hydrogen in liquids at low temperature and high pressure have been reduced by a thermodynamic relation similar to the Krichevsky-Kasamovsky equation but allowing for the variation of activity coefficient with hydrogen concentration.

The parameters appearing in this relation have been partially correlated on the basis of a very simple solution model. The results show that under comparable conditions the solubility of hydrogen in simple inorganic solvents (argon, nitrogen and carbon monoxide) is considerably larger than that in light hydrocarbons (ethane, ethylene. propane and propylene), with methane falling in between these groups.
