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 diaminoether wherein at least one amino group is a tertiary amine whereby H.sub.2 S is selectively absorbed from the mixture.
A novel class of diaminoether compounds wherein one amino group thereof is a tertiary amine in N-heterocyclic form and the other amino group is a severely sterically hindered secondary amino group may be prepared by a three-step process and are useful in the selective removal of H.sub.2 S from mixtures containing H.sub.2 S and CO.sub.2.

A method for determining absorbent molecules that are effective for the property of acid gas removal from feedstreams comprising a) determining a set of known molecules that are effective for acid gas removal, b) defining descriptive parameters (descriptors) that correlate with the structure of molecules with known acid gas removal, c) assigning a value to each descriptor for each of the known molecules and developing a quantitative structure and property relationship (QSPR), and d) generating molecular structures that will be effective for acid gas removal from the structure and property relationship.
