摘要： While some triazines have low reactivity, a method and composition is described for improving their reactivity. The H2S scavenging composition and method utilizes a tertiary amine to catalyze the scavengers with slower kinetics to achieve improved results over traditional systems with the scavenger alone. A hydrogen sulfide scavenging composition comprises: a tertiary amine as a catalyst in at least one of (i) a triazine scavenger selected from the group consisting of: methyl amine, C2-C5 alkyl amine, dimethylaminopropylamine, isopropanolamine, aniline, cyclohexylamine, isobutanolamine and methoxypropylamine triazines/bisoxazolidines; or (ii) an aldehyde-based scavenger such as glyoxal.

摘要： Unleaded aviation gasoline. An aviation gasoline fuel blend includes an unleaded aviation gasoline base fuel, with an effective amount of selected alkyl benzenes to improve the functional engine performance to avoid harmful detonation sufficient to meet or exceed selected standards for detonation performance requirements in full scale aircraft piston spark ignition engines designed for use with Grade 100LL avgas. Suitable alkylated benzenes may include a mixture of xylene isomers. Aromatic amines, such as m-toluidine, may also be added to increase MON. Base fuels may be a high quality aviation alkylate, or may be a commercial iso-octane, or a mixture of high quality aviation alkylate enhanced by iso-octane, or by commercial iso-octane mixtures, and may include iso-pentane or butane or both iso-pentane and butane in sufficient quantity to provide appropriate vapor pressure for the final fuel blend.

摘要： Concentrate for the manufacture of unleaded aviation gasoline. High quality aviation alkylate, or similar base fuel is blended with selected aromatic solvents, including alkyl benzenes effective to improve the functional engine performance to avoid harmful detonation in aircraft piston engines. Monoalkylated benzenes such as toluene and ethylbenzene are utilized in combination with dialkylated benzenes, such as xylenes. Aromatic amines, for example p-toluidine and m-toluidine, may be added to increase MON. Alcohols such as ethanol and/or methanol may be added in effective amounts to produce unleaded AVGAS which meets a required freeze point. Amounts of toluene to p-toluidine, and/or of the amount of p-toluidine to m-toluidine may be in a controlled ratio in amounts effective to produce unleaded AVGAS which meets a required freeze point. Isopentane and/or butane may be included to provide a required vapor pressure profile.

摘要： Unleaded aviation gasoline. An unleaded aviation gasoline includes a blend of high octane alkylate, an effective amount of selected alkyl benzenes, and selected aromatic amines sufficient to improve the functional engine performance to avoid harmful detonation sufficient to meet or exceed selected standards for detonation performance requirements in full scale aircraft piston spark ignition engines designed for use with Grade 100LL avgas. Suitable alkylated benzenes may include a mixture of xylene isomers. Selected aromatic amines, such as N-methyl-p-toluidine, are used to increase performance. The high octane alkylate may be an aviation alkylate, or iso-octane, or both, and may utilize high octane alkylates having a motor octane number of between about ninety-seven (97) and about one hundred (100). Suitable amounts of iso-pentane, n-butane, and iso-butane may be used for providing vapor pressure in a commercially acceptable range.
