  57 The present invention relates to a process for selectively preparing severely sterically hindered or cyclic tertiary polyalkylene aminoether alcohols by reacting (a) one or more secondary acyclic or heterocyclic amino compounds with (b) a polyalkylene ether glycol in the presence of a hydrogenation catalyst at elevated temperatures and pressures. The resulting tertiary aminoether alcohols are useful n acid gas scrubbing processes, particularly in the selective removal of H2S from gaseous streams containing CO2 and H2S.

  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.
