| Abstract: | The gas chromatography-mass spectrometry(GC/MS)detection method of trace impurities in diethyl phthalate(DEIP)was established.The DEIP was separated by vacuum distillation and the trace impurities were analyzed with GC/MS.The 11 kinds of main impurities were identified with production technology,spectrum database and artificial retrieval.The 11 kinds of main impurities contents were given using area normalization method.The method was benefited to production and process optimization. |
| Keywords: | diethyl m-phthalate GC/MS vacuum distillation |
