摘要：
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 strongly basic tertiary amino compound having a pK.sub.a at 20.degree. C. greater than 8.6 and a boiling point at 760 mm greater than 180.degree. C. whereby H.sub.2 S is selectively absorbed from the mixture.
