摘要
(EP2478077) 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.

(EP2478077) 1. A fuel composition for internal combustion engines comprising,  a major portion of an alcohol blended gasoline comprising (i) at least one alcohol selected from a group comprising of ethanol, butanol, and methanol in amount 5 to 90% and (ii) gasoline in amount of 95 to 10%; and  a minor portion of a corrosion inhibitor formulation comprising i. a corrosion inhibitor, comprising a reaction product of (a) a fatty acid selected from a group comprising of oleic acid, linoleic acid, mystiric acid, stearic acid, palmitic acid and ricinoleic 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, methyl soya ester; iii. a dispersing agent, wherein the dispersing agent is a sulfonate compound; and iv. a viscosity reducing agent selected from a group comprising of ethanol, isopropanol, and propargyl alcohol, wherein the corrosion inhibitor formulation is present in the fuel composition in the range of 10 to 100 ppm. 2. The fuel composition as claimed in claim 1, wherein in the corrosion inhibitor formulation, the reaction product of the fatty acid and the azomethine compound is present in the range of 100 to 10,000 ppm, the fatty acid oil or ester is present in the range of 80 to 98%, the dispersing agent is present in the range of 10-500 ppm, and the viscosity reducing agent is present up to 5%. 3. The fuel composition as claimed in claim 1, wherein the fuel composition is suitable for corrosion prevention of metallurgies comprising carbon steel, copper, brass, lead and zinc involved in fuel storage tanks, vehicles fuel tanks during transportation, and fuel distribution systems. 4. The fuel composition as claimed in claim 3, wherein the fuel composition has moisture content of the alcohol in the range of 0- 5%. 5. A corrosion inhibitor formulation for internal combustion engines comprising i) a corrosion inhibitor, comprising a reaction product of (a) a fatty acid selected from a group comprising of oleic acid, linoleic acid, mystiric acid, stearic acid, palmitic acid and ricinoleic acid and (b) an azomethine compound derived from a condensation reaction between a carbonyl compound and an amine compound in the ratio of 1:1 to 2: 1. ii. a fatty acid oil or ester selected from a group comprising of castor oil, palm oil, soyabean oil, methyl soya ester; iii. a dispersing agent, wherein the dispersing agent is a sulfonate compound; and iv. a viscosity reducing agent selected from a group comprising of ethanol, isopropanol, and propargyl alcohol. 6. The corrosion inhibitor formulation of claim 5, wherein the carbonyl compound is selected from a group comprising of cinnamaldehyde, furfuraldehyde, benzaldehyde, and salicylaldehyde. 7. The corrosion inhibitor formulation of claim 5, wherein the amine compound is selected from a group comprising of imidazoline, hexadecylamine, 2- ethylhexyl amine, cyclohexylamine, 1,4, diaminobutane, 1,6 diaminohexane, 1,3 diaminopropane, 1,4 diphenylenediamine, 4-aminophenol, ethylenediamine, and phenylenediamine. 8. A method for preparing a corrosion inhibitor formulation comprising the steps of, i. obtaining a reaction product of (a) a fatty acid selected from a group comprising of oleic acid, linoleic acid, mystiric acid, stearic acid, palmitic acid and ricinoleic acid and (b) an azomethine compound derived from a condensation reaction between a carbonyl compound and an amine compound, to give a corrosion inhibitor; ii. dissolving the corrosion inhibitor in a fatty acid oil or ester, wherein the fatty acid oil or ester is selected from a group comprising of castor oil, palm oil, soyabean oil, and methyl soya ester; iii. adding a dispersing agent, wherein the dispersing agent is a sulfonate compound; and iv. adding a viscosity reducing agent to give the corrosion inhibitor formulation, wherein the viscosity reducing agent is selected from a group comprising of ethanol, isopropanol, and propargyl alcohol. 9. The method as claimed in claim 98, wherein the carbonyl compound is selected from a group comprising of cinnamaldehyde, furfuraldehyde, benzaldehyde, and salicylaldehyde and the amine compound is selected from a group comprising of imidazoline, hexadecylamine, 2-ethylhexyl amine, cyclohexylaminej 1,4, diaminobutane, 1,6 diaminohexane, 1,3 diaminopropane, 1,4 diphenylenediamine, ethylenediamine, and phenylenediamihe.
