Abstract:
The selective removal of H.sub.2 S gas from a normally gaseous mixture containing H.sub.2 S and CO.sub.2 is accomplished by contacting the gaseous mixture with an absorbent solution comprising a severely sterically hindered secondary aminoether alcohol having a cumulative .sup.- -E.sub.s value (Taft's steric hindrance constant) greater than about 1.75 whereby H.sub.2 S is selectively absorbed from the mixture.
