HYDROGEN SULFIDE SCAVENGERS AND METHODS FOR REMOVING HYDROGEN SULFIDE FROM ASPHALTAbstract:A method for reducing hydrogen sulfide in asphalt includes adding a hydrogen scavengercomposition to the asphalt. The hydrogen sulfide scavenger includes a polyaliphatic amine having the formula I: (I); R is an aliphatic radical and n is from about 0 to about 15. A method for treating asphalt and a hydrogen sulfide scavenger are also provided.Figure 1
