  • Patent number: 4665234
    Abstract: A novel class of severely sterically hindered secondary aminoether alcohols of the general formula: ##STR1## are prepared wherein R.sub.1 and R.sub.2 are each selected from the group consisting of alkyl and hydroxylalkyl radicals R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are each selected from the group consisting of hydrogen, alkyl and hydroxyalkyl radicals, with the proviso that at least one of R.sub.4 or R.sub.5 bonded to the carbon atom directly bonded to the nitrogen atom is an alkyl or hydroxyalkyl radical when R.sub.3 is hydrogen, x and y are each positive integers ranging from 2-4 and z is a positive integer ranging from 1-4. The compounds are useful in the selective removal of H.sub.2 S from mixtures containing H.sub.2 S and CO.sub.2.
