Take an appropriate amount of maleic anhydride and react with bis(trimethylsilyl)trifluoroacetamide (BSTFA) at a temperature of 65 ℃
10min, make the impurity compounds in the sample and BSTFA form stable derivatives. After the sample is vaporized under the selected chromatographic operating conditions
After chromatographic column separation, hydrogen flame ionization detector detection, internal standard method quantification, calculate the total impurity content, subtract 100% of the total impurity content (quality
Amount fraction) to obtain the content of maleic anhydride.
