Donham, J E

An amino phosphonic acid is made dispersible in organic solvents to form clear solutions by reacting the acid in water solution with an imidazoline having an alkyl side chain containing about 8 carbon atoms. The resulting reaction product is highly soluble in a wide variety of organic solvents. It is useful as a scale inhibitor, corrosion inhibitor, paraffin solvent and inhibitor, and acid retarder in oil wells. It has other uses in the oil field and outside the oil field. (2 claims)
