Patent ID: 7338541

Claim:
A fuel composition for internal combustion engines, said fuel composition comprising: (a) at least about 5% of one or more fuel hydrocarbons; and (b) at least about 10 ppm of one or more nonlinear primary aliphatic alcohol derivatives, wherein the alcohol moieties of said one or more nonlinear primary aliphatic alcohol derivatives have at least about 11 carbon atoms and having the formula: wherein C b H 2b-2 is a linear saturated hydrocarbyl and D, L, Q and R are substituents; D is CH 3 , b is an integer selected such that the total carbon content of the alcohol moiety of said nonlinear primary aliphatic alcohol derivatives are from about 11 to about 21 carbon atoms, L is a moiety having the general formula: wherein one of X and Y and Z is in independently selected from the group consisting of: 1) CH 2 OC(O)R′ wherein R′ is selected from H, CH 3 , CH 2 CH 3 , CH 2 CH 2 CH 3 , CH 2 OH, CHOHCH 3 , CH═CHC(O)OH, CH 2 CH 2 C(O)OH, or C 6 H 5 C(O)OH; 2) CH 2 O(alkoxy) n H, n represents an average of alkoxy units and has a value of from about 0.01 to about 5; 3) CH 2 OCH 2 CH(OH)CH 2 OCH 2 CH(OH)CH 2 OH; 4) CH 2 OCH 2 CH 2 C(O)OH; and 5) mixtures thereof; any of X and Y and Z which is not independently selected from the group consisting of CH 2 OC(O)R′ wherein R′ and n are defined as above; CH 2 O(alkoxy) n H; CH 2 OCH 2 CH(OH)CH 2 OCH 2 CH(OH)CH 2 OH; CH 2 OCH 2 CH 2 C(O)OH and mixtures thereof, is H; E, G and Q are selected from H, methyl, ethyl, propyl butyl, and mixtures thereof provided that E, G and Q are not all H and such that no carbon atoms are quaternary; R is selected from the group consisting of H, methyl ethyl, propyl, butyl, and mixtures thereof.
