Quantitative Analysis Of Dicyclohexylamine And Impurities

HPLC-ELSD was used to study the quantitative analysis of dicyclohexylamine. The recoveries were 98.2%-102.45% with RSD of 8.39-9.3%. In addition, HECEDA was used to study the simultaneous quantitative analysis of aminophenol and aniline. The limits of quantification were 1 and 0.5ng, and the linear ranges were 0-40 mg/L and 0-20 mg/L, respectively. The accuracy and precision of the analytical method can meet the requirements of product quality testing.
