<p>A composition and method are disclosed for sweetening gaseous or liquid hydrocarbons, aqueous systems and mixtures thereof with a non-regenerative scavenger having the chemical formula <CHEM> wherein n is an integer from 1 to 6 and R1, R2, R3 and R4 are independently selected as straight chain or branched alkyl groups containing from 1 to 20 carbon atoms, aryl groups. alkylaryl groups, heterocyclic groups, cycloalkyl groups, or (CH2)n-OR5 groups with R5 being hydrogen or an alkyl group having from 1 to 8 carbon atoms and n being an integer from 1 to 6. Altematively, R1 and R2 may be linked together and R3 and R4 may be linked together to form alkylene rings having from 4 to 5 carbon atoms.</p> |
