| 中文摘要: |
| 采用气相色谱（GC）或高效液相色谱（HPLC）对防老剂4020，3100和RD进行检测和分析。防老剂4020的鉴别可按国家标准指标和GC谱进行；防老剂3100的鉴别除检测国家标准指标外，还应检测3种对苯二胺质量分数和铁质量分数；防老剂RD的鉴别除检测国家标准指标外，还应检测二聚体质量分数和二、三、四聚体总质量分数。建议下游企业用GC或HPLC对防老剂有效成分进行检测。 |
| 英文摘要: |
| In this work，three amine antioxidants，4020，3100 and RD，were analyzed using gas chromatography （GC） and high performance liquid chromatography （HPLC）.Antioxidant 4020 could be identified according to national standards and GC spectrum.However，for antioxidant 3100，besides testing according to the national standards，additional tests were required to determine the mass fractions of three kinds of p-phenylenediamine and iron element.In the case of antioxidant RD，additional tests were carried out to determine the dimer content and the total amount of dimer，trimer and tetramer.It was recommended that downstream companies conducted the tests of active ingredients of antioxidants by GC and HPLC. |
