Aviation gasolines and additives may have manganese-containing anti-knock components. The scavengers herein mitigate the possible deleterious effects from using the manganese-containing anti-knock. The scavengers include molecules with a central atom of a Group 15 element other than nitrogen. Entities that are attached to the central atom are electron withdrawing entities including electron deficient atoms and electron deficient functional groups.

Manganese scavengers that minimize octane loss in aviation gasolines

Aviation fuel formulations receive many benefits when a manganese-containing additive is incorporated in that composition. However, to the extent that the use of a manganese-containing compound may result in the formation of engine deposits during combustion, it is beneficial to further provide a scavenger compound to the fuel composition. This scavenger compound may include a phosphorus-containing compound, an organobromide compounds, and/or a tricarbonyl compound.

Aviation fuel additive scavenger

An aviation fuel is formulated with manganese-containing compounds. The composition may include relatively high amounts of manganese up to about 500 mg Mn/l. A manganese-containing additive may reduce the smoke created during the combustion of the aviation fuel. Additionally, the aviation fuel composition may include manganese to improve octane and include a phosphorus-containing scavenger to reduce manganese oxide engine deposits. Further, isooctane is added in order to, with the manganese-containing compound, improve the octane number of the fuel.
