HYDROGEN SULFIDE SCAVENGERS AND METHODS FOR REMOVING HYDROGEN SULFIDE FROM ASPHALT

A method for reducing hydrogen sulfide in asphalt includes adding a hydrogen scavenger composition to the asphalt. The hydrogen sulfide scavenger includes a polyaliphatic amine having the formula I: H2NRNH-(RNH)n-H I R is an aliphatic radical and n is from about 0 to about 15. A method for treating...
