IMPROVED LEADED AVIATION GASOLINE

摘要

Aviation gasolines having an enhanced peak indicated mean effective pressure are provided by admixing with a leaded base aviation gasoline an aromatic amine of the formula NH₂-Ar-(R¹)_n wherein R¹ is selected from C₁-C₁₀ alkyl, halogen, and mixtures thereof provided that when R¹ is alkyl it occupies the meta- or para-positions on the aromatic ring, Ar is a phenyl aromatic group and n is an integer from 0 to 3 to provide an aviation gasoline having a peak indicated mean effective pressure as determined by ASTM D-909 of greater than about 200 psi.
