Oxygenates are hydrocarbons containing oxygen atoms as part of their molecular structure. Some oxygenates are octane boosters that support the complete combustion of gasoline (anti-knocking) for reducing carbon monoxide (CO) emissions from vehicles.1 Methyl tertiary butyl ether (MTBE) is a widespread octane enhancer that was established in the 1970s. However, because of the considerable risk of contamination to groundwater due to its high solubility, MTBE was banned in the US in the early 2000s. Several alternatives to MTBE are available as anti-knock agents, such as ethanol, ethyl tertiary butyl ether (ETBE), tertiary amyl methyl ether (TAME) or tertiary amyl ethyl ether (TAEE). Neverthele
