Compositions Containing Diesel and Fatty Acid Methyl Ester/Maleic Anhydride/Esters (FAME/MA/Esters) and the Use of FAME/MA/Esters to Improve the Lubricity of Diesel

Abstract

A composition containing diesel (e.g., containing less than about 15 ppm sulfur) and fatty acid methyl ester/maleic anhydride/esters (FAME/MA/esters), wherein the FAME/MA/esters are prepared by a method involving reacting FAME with MA to form FAME/MA and reacting FAME/MA with alkyl alcohol to form FAME/MA/esters; wherein the FAME is conjugated. The FAME/MA/esters are produced from tung oil or from plant oils in which the unsaturated fatty acids have been converted to conjugated fatty acids. Also a method of improving the lubricity of diesel, involving combining diesel and FAME/MA/esters, wherein the FAME/MA/esters are prepared by a method involving reacting FAME with MA to form FAME/MA and reacting FAME/MA with alkyl alcohol to form FAME/MA/esters; wherein the FAME is conjugated.
