The solubility of CO2, N2, and H-2 mixtures in N-methyl-pyzrolidone wa
s measured by means of an original set-up described in a previous pape
r [1], modified far synthesizing and analyzing the gaseous mixture and
the solution. The effect of gas mixing was observed by comparing the
solubility of the mixed gas, with that of the pure gas, at the same te
mperature and partial presure.
