Gas Chromatography for the Determination of Benzene Anhydride Content in Distillation Residues
In order to clarify the recycling value of distillation residues,a gas chromatography method for the determination of benzene anhydride in distillation residue is established.The distillation residue is separated by gas chromatography,detected by hydrogen flame ionization detector,and quantified by internal standard method.The results show that the target benzene anhydride has a good linear relationship in 2 to 18 mg/mL range(R2 of 0.999 9),high precision(relative standard deviation of 0.25%)and high accuracy(sample spike recovery rate is 100.00%to 104.3%).This method is accurate and simple,and can be used for the determination of benzene anhydride content in distillation residue.
