Scope
This document specifies the method for determining aromatic hydrocarbons in the aqueous phase of methanol-produced low-carbon olefins using purge and trap/gas chromatography-mass spectrometry.
This document is applicable to the determination of eight kinds of aromatic hydrocarbons in the aqueous phase of methanol-produced low-carbon olefins, including toluene, ethylbenzene, p-xylene, m-xylene, o-xylene, 1,3,5-trimethylbenzene, 2-ethyl toluene, and 1,2,4-trimethylbenzene.
