Abstract
Oleophilic polyoxyalkylene monoethers having reduced water affinity are disclosed. The monoethers have a hydrocarbyl residue, a polyoxyalkylene moiety, and a hydroxyl end group. The monoethers contain less than about 6 mole percent of alkoxylated unsaturates, and preferably less than about 5 mole percent of polyoxyalkylene diols. The monoethers offer substantial advantages for fuel compositions, particularly reduced water affinity. By using deposit-control additives based on the monoethers, formulators can offer better fuels for cleaner engines.
