Scope

This Standard specifies the determination method of ester compounds (ethyl acetate,
sec-butyl acetate, dimethyl carbonate) in the motor gasoline.
This Standard is applicable to determine the motor gasoline, ester compounds with
concentration of 50mg/L ~ 2000mg/L; this Method can also determine beyond such
content range; however, the precision is not investigated.
This Standard is not applicable to alcohol-containing gasoline; Certain alcoholic
compounds (such as methanol, ethanol, tert-amyl alcohol, and sec-butanol) and
ketone compounds (such as acetone and butanone) may interfere the determination
of ester compounds.

Summary	This standard specifies the determination method of vehicle gasoline ester ester compounds (including ethyl acetate, sec-butyl acetate, dimethyl carbonate). This standard applies to vehicle gasoline, ester compounds measured concentration of 50 mg/L ~ 2000 mg/L, beyond the scope of this method can also be measured by this method, but the precision is not investigated. This standard does not apply to alcohol-containing gasoline. Certain alcoholic compounds (such as methanol, ethanol, t-amyl alcohol and sec-butanol) and ketones (such as acetone and methyl ethyl ketone) may interfere with the determination of vinegar compounds.
