Composition to reduce phase separation in automobile fuels

摘要

An additive for gasoline, especially gasoline containing ethanol in an amount of up to about 15%, reduces the potential for phase separation of water from the gasoline. The additive has two components. The first component consists essentially of glycol butyl ether. The second component consists essentially of nonylphenol polyethylene glycol ether with minor amounts of polyethylene glycol and dinonylphenyl polyoxyethylene. Typically, the additive has the first component present in an amount in the range of from about 90 to about 95% by volume, with the balance being the second component. The additive is effective when added to the gasoline in an amount in the range of from about 0.52% to 0.63% by volume.
