摘要: A fast and simple 1H NMR spectroscopic method was developed for the concentration measurement of aromatic, olefinic aliphatic fractions in gasoline samples. Simultaneously, individual components such as benzene, methyl tert-butyl ether several dienes could be determined. The relies on only a few, well-established assumptions about molecular compositions is therefore applicable to broad range gasolines. It well suited laboratories with high sample throughput since time short all concentrations are determined within one experiment. applied commercial gasolines samples used European round robin tests. Comparisons test results showed excellent agreement.
