The invention relates to a method for analyzing and detecting the contents of DADN, SEX and RDX in HMX synthesis byproducts, and belongs to the technical field of energetic material quality analysis and detection. The method is a method for detecting the contents of DADN, SEX and RDX in byproducts formed in the HMX preparation process by adopting an external standard method, a byproduct sample is dissolved in an organic solvent to form a byproduct solution, the component content is analyzed through a reversed-phase liquid chromatographic column, and the mobile phase is acetonitrile, water and an ultraviolet detector. Comparing and correlating the retention time and the peak area of each peak position in the liquid chromatogram of the byproduct with the retention time and the peak area on DADN, SEX and RDX standard sample liquid chromatograms under the same chromatographic condition, and confirming and calculating the content of corresponding components. The method can be used for rapidly and accurately detect
