Abstract (en)
Unsymmetrical dialkyl carbonates are blended with hydrocarbon liquid fuels such as gasoline to provide fuel compositions having improved octane number and anti-knock characteristics. The unsymmetrical dialkyl carbonate may be methyl t-butyl carbonate, ethyl t-butyl carbonate, methyl t-amyl carbonate, or ethyl t-amyl carbonate. <IMAGE>
