| 中文摘要: |
| 研究差示扫描量热（DSC）法测定防老剂4020的纯度。确定的测试条件如下：取样量 2～3 mg，升温速率 0.7 ℃·min-1，保护气体流速 20～40 mL·min-1。试验表明DSC法测定防老剂4020的纯度与常规气相色谱法测定结果很接近，同时该方法操作简单、用时短，对环境友好。 |
| 英文摘要: |
| Determination of purity of antioxidant 4020 by differential scanning calorimetry（DSC） method was studied.The test conditions were as follows：sample quality 2～3 mg，temperature rise rate 0.7 ℃·min-1，protective gas flow rate 20～40 mL·min-1.The test showed that the purity of antioxidant 4020 measured by DSC method was very closed to that of conventional gas chromatography（GC） method.At the same time，this method was simple to operate，short in time and environmentally friendly. |
