ABSTRACT:
Disclosed is a reaction product and method for making same for use in supressing the ability of solubilized copper, iron, cobalt, nickel, chromium and manganese present in hydrocarbon liquids, such as gasoline and fuel oil, to catalyze oxidative degradation. The reaction product is obtained by reacting a 1,2-alkane diamine, a 2,4-dione and an ortho-hydroxy aromatic aldehyde, in stoichiometric proportions, preferably in an inert liquid medium. A preferred reaction product is that obtained by reacting ethylenediamine, 2,4-pentanedione and salicylaldehyde in a 1 to 1 to 1 mole ratio.
