FUEL SYSTEM ICING INHIBITORS: THE SYNTHESIS OF ESTERS OF OXAACIDS

摘要: ABSTRACT Currently ethylene glycol mono methyl ether (EGME) and diethylene (DiEGME) are used as fuel system icing inhibitor additives in both military commercial aircraft. These compounds toxic at the concentrations that required for effective deicing When systems sumps, filters storage tanks drained, they contain EGME/DiEGME create hazards personnel. Ethyl esters synthesized from oxaacids have been identified possible additive replacements. were ethanol by an acid catalyzed Fischer esterfication method The products infrared spectrometry, nuclear magnetic resonance elemental analysis Physical characterization included boiling point determination refractive index. tested oxaesters found to be stable least two years accelerated tests. Octanol-water partition coefficients determined indicate com...
