Abstract: A fuel composition is described. The composition contains a hydrocarbon-based fuel boiling in the gasoline or diesel range; a carrier fluid comprising an alkyl polyethoxylate having the following structure: where each R2 and R3 is independently hydrogen, C1-C4 hydrocarbyl group, or C1-C3 alcohol, where R1 is C4-C100 hydrocarbyl group, carboxyl group, ether group, thioether group, or aromatic group, wherein x is from 1 to 20, or a hydrocarbyl phenol having the following structure wherein R is a hydrocarbyl group from C4-C100; an amine-based detergent given by formula 2, R4—O—(CH2)y—NHR5, where the amine-based detergent is present in about 10 ppm to about 750 ppm by weight based on total weight of the fuel composition; where R4 is a hydrocarbyl group having 8 to 20 carbons, R5 is hydrogen or (CH2)zNH2 moiety, and where y, z are independently integers having a value of 2 or greater; and one or more nitrogen-containing detergent.

Abstract: Disclosed are polyisobutenyl alcohols and substituted polyisobuentyl alcohols of the formula: wherein n is an integer from 5 to 90, R is selected from the group consisting of hydrogen, haloalkyl, alkoxycarbonyl and substituted aryl wherein at least one substituent group of the substituted aryl is selected from cyano, nitro and alkoxycarbonyl.

Abstract: Disclosed is a method for preparing a hydroxyl functionalized polymer from a Lewis acid promoted carbonyl-ene reaction comprising: selecting a vinylidene terminated polyolefin having a number average molecular weight from about 950 to about 5000 and having a terminal vinylidene content greater than 50 mole percent; selecting a carbonyl enophile; selecting a Lewis acid; and contacting the components in step a), b) and c) under reactive conditions to form the hydroxyl functionalized polymer.
