    Abstract: Hydrogen sulfide gas evolution from water or hydrocarbons, especially during storage or transport of petroleum residua is suppressed by the incorporation of an effective amount of a diamine of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are independently an alky radical containing 1 to 14 carbon atoms, (CH.sub.2).sub.n --OR.sub.6 or cycloalkyl containing 5 or 6 carbon atoms and R.sub.5 is hydrogen or methyl. R.sub.1 and R.sub.2 and R.sub.3 and R.sub.4 can be alkylene groups joined together with their respective adjacent N to form a heterocyclic ring. R.sub.6 is hydrogen or an alkyl radical having 1 to 5 carbon atoms and n is an integer of 1 to 5.
