This standard specifies a method for the determination of trace dimers and residual extractants in industrial butadiene by Gas chromatography, CG. It is suitable for the detection of trace dimers such as 4-vinylcyclohexene and 1,2-divinylcyclobutane in industrial butadiene and residual extractants such as acetonitrile and N, N-dimethylmethylamide. The minimum determination concentrations are 5 mg/kg and 1 mg/kg respectively. This standard provides a scientific determination method for the mass detection of industrial butadiene, which helps to ensure the purity and mass of the product.
