| 中文摘要: |
| 采用气相色谱-质谱联用、傅里叶转换红外光谱和热重分析方法，建立橡胶防老剂BLE-W的定性定量方法。试验结果证明：所建立的定性方法准确；BLE的定量结果与抽提法的相对偏差小于1%，BLE、碳酸钙和白炭黑含量测试的相对标准偏差（重复6次）分别为0.32%，3.8%和0.38%，均小于4%，精度高，结果满意，可以有效地对入厂的防老剂BLE-W进行质量控制。 |
| 英文摘要: |
| Taking gas chromatography-mass spectrometry（GC-MS），Fourier transform infrared spectroscopy（FTIR） and thermogravimetric（TG） analysis method，a qualitative and quantitative method for rubber antioxidant BLE-W was established.The test results showed that the established qualitative method was accurate.The relatively deviation between quantitative results of BLE and the extraction method was below 1%.The relative standard deviations（repeated 6 times） of BLE，calcium carbonate，and white carbon black content tests were 0.32%，3.8%，and 0.38%，respectively，all less than 4%.The accuracy was high and the results were satisfactory，which could effectively control the quality of the incoming antioxidant BLE-W. |
