Abstract:
A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
Abstract:
The present invention relates to a gasohol fuel composition that prevents corrosion of the metallurgies involved in fuel storage tanks, vehicle fuel tanks, fuel distribution systems, and transportation systems. The novel gasohol fuel composition comprises of a major portion of an alcohol blended gasoline fuel and a minor portion of a corrosion inhibitor formulation, wherein the corrosion inhibitor formulation comprises of (i) a reaction product of (a) a monosaturated fatty acid; and (b) an azomethine compound derived from a condensation reaction between a carbonyl compound and an amine compound; (ii) a fatty acid oil or ester selected from a group comprising of castor oil, palm oil, soyabean oil, and methyl soya ester; (iii) a dispersing agent, the dispersing agent being a sulfonate compound; and (iv) a viscosity reducing agent selected from a group comprising of ethanol, isopropanol, and propargyl alcohol.
Abstract:

Abstract:
A method of inhibiting deposit formation in a jet fuel at temperatures above 150° C., whilst not substantially adversely affecting the water separability of the jet fuel. The method includes the step of adding at least one copolymer, terpolymer or polymer of an ester of acrylic acid or methacrylic acid or a derivative thereof to the jet fuel; wherein the copolymer, terpolymer or polymer of an ester of acrylic acid or methacrylic acid or derivative thereof is copolymerized with a nitrogen-containing, amine-containing or amide-containing monomer; or the copolymer, terpolymer or polymer of an ester of acrylic acid or methacrylic acid or derivative thereof includes nitrogen-containing, amine-containing or amide-containing branches.
