Abstract:
A water-free fluid mineral acid salt composition of fatty acid amine derivatives for use in hot asphalt formulations comprising a blend of:a) about 25% to about 95% by total weight of the blend of a fatty acid amine derivative selected from the group consisting of amidoamines, imidazolines, polyamidoamines, amidoamine/imidoamines, polyimidazolines, and combinations thereof;b) about 4% to about 35% by total weight of the blend of a mineral acid, wherein said mineral acid is added to the blend at temperature and pressure adequate to eliminate water from the blend;c) about 1% to about 70% by total weight of the blend of a polar organic solvent having a boiling point higher than about 160.degree. C., wherein said polar organic solvent is selected from the group consisting of polyalkanols, polyalkanolamines, polyalkanol ethers, polyalkanol esters, and combinations thereof; andd) up to about 70% by weight of the blend of a second fatty acid amine derivative having a different chemical structure than the fatty acid amine derivative (a), wherein said second fatty acid amine derivative is a member selected from the group consisting of fatty polypropylene polyamines, fatty ethoxylated polypropylene polyamines, fatty amidoamines, fatty imidazolines, fatty polyamidoamines, fatty amidoamine/imidoamines, fatty polyimidazolines, and combinations thereof.
