Oxygenated compounds can be present in various hydrocarbon matrices either because they were purposely added (e.g. gasoline) or because they are naturally present or formed during catalytic processes (e.g. polymer production). In gasoline, oxygenated compounds are added as ‘anti-knock’ agents to increase the octane number and decrease emissions by replacing organo-lead compounds. The type and concentration of oxygenated compounds must be measured in reformulated gasolines as part of ongoing product quality assessment, and to confirm the oxygenated components have been added in the correct amounts according to regulatory requirements. ASTM D4815 is frequently chosen as the standard method for the determination of oxygenated compounds.
