Claim:
1. A method for scavenging hydrogen sulfide from a fluid comprising: contacting the fluid with an effective amount of a protic composition to reduce the amount of hydrogen sulfide as compared to an identical method absent the protic composition, the protic composition consisting of: a protic solvent; optionally a base selected from the group consisting of sodium hydroxide, potassium hydroxide and combinations thereof; and a non-nitrogen-based compound having a formula selected from the group consisting of: wherein each R 1 , R 2 , R 3 , and R 4 are the same or different and are selected from the group consisting of hydrogen, an alkyl, an alkenyl, an aryl, an acyl, a halogen, a hydroxyl, an alkyl ester, an aryl ester, an alkyl ether, an aryl ether, a hydroxymethyl, an anhydride, and a sulfide, and where the fluid is selected from the group consisting of: an aqueous phase, a gaseous phase, a mixture of an aqueous phase and a gaseous phase, a mixture of an aqueous phase and a hydrocarbon phase, and a mixture of an aqueous phase, a gaseous phase and a hydrocarbon phase.
