| Abstract | To improve octane performance and reduce emissions, MTBE and to lesser degree ETBE and TAME are blended into gasolines. These oxygenates coelute with hydrocarbon components of gasoline in GC analysis. It is known that oxonium ions are formed in the electron impact mass spectrometry Of aliphatic alcohols and ethers. The base ions of t-BuOH, MTBE, ETBE, TAME, and BEE are either mit 59 or 73 ions, and fragment ions of alkanes, alkenes, and naphthenes are at mit 41, 43, 55, 57, 69, 71, 83, and 88. The maximum background m/z59 and 73 ion abundances of three diluted (1:20) gasolines which are used to determine percent oxygenates in gasoline were less than 0.04% that of the lowest analyte standard used to determine the linear regression coefficients of these ethers. The background mit 59 and 73 traces of undiluted gasoline were also studied. An ACN/gasoline partitioning cleanup technique was used to remove hydrocarbon interferences of less than 2% (v/v) oxygenated gasoline prior to identification by GC/MS. |
