Abstract
A stabilized nano-Fe-iron-crown ether complex is formed by preparing a solution of an iron salt and an oligomer crown compound in dialkylamine or diethylamine. Sodium tetrahydroboron (NaBH) and dialkylamine or ethylendiamine are added at a temperature of 0-10° C. The mixture is heated to room temperature and boiled, thereby converting the formed iron (II)-borhydride complex (Fe(BH)) to a crown ether-iron-hydride complex [CWFe].(2H). At higher temperature this last complex is converted to the Fe-crown nanocomposite complex. The prepared nanoparticle Fe° complex may be stabilized by inclusion into a cavity of a macrocyclic compound, and may be (1) added to diesel fuel to reduce NOx emissions upon combustion of that fuel; (2) added to lubricating oils as an anti-corrosion additive; and (3) used as an additive to secondary recovery processes within liquid hydrocarbon formations to increase the sweep efficiency and recovery factor of water-flooding operations.
