Stogryn, E L; Sartori, G; Savage, D W

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 di-secondary aminoether wherein each amino group has a severely sterically hindered secondary amino moiety whereby H/sub 2/S is selectively absorbed from the mixture.
