Determination of Diethylmalonate in Crude Ester by Gas Chromatography

  title={Determination of Diethylmalonate in Crude Ester by Gas Chromatography},
  author={He Yong-mei},
A method for determination of the content of diethylmalonate in Crude Ester was established using capillary gas chromatography by DB-624 gas chromatography.O-xylene was used ACas the internal standard.In this method,FID detector was used,and the quantitative method was internal standard method.The experiment results indicate that the method had good precision,and the average of relative standard deviation in sample was 1.32%.The average recovery was 98.25%.The linear correlation coefficient was… CONTINUE READING
