POLYOXYALKYLENE MONOETHERS WITH REDUCED WATER AFFINITY

摘要

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 depositcontrol additives based on the monoethers, formulators can offer better fuels for cleaner engines.
