| 中文摘要: |
| 研究硫化胶中橡胶油含量的测定。采用溶剂抽提法得到硫化胶的抽出物，并对其抽出物进行硅胶柱层析，建 立了硫化胶中橡胶油含量的测定方法。该方法测定的硫化胶中橡胶油质量分数最大相对标准偏差为2. 3%，回收率为 88. 0%～104. 1%。该方法操作简便，重复性好，结果准确、可靠。 |
| 英文摘要: |
| The method of determination of the rubber oil content in the vulcanizate was established by using solvent extraction and silica gel column chromatography. The vulcanizate sample was firstly extracted by solvent and then the extractive substance was separated out by chromatography. The experimental testing results showed that the maximum relative standard deviation of the mass fraction of the rubber oil in the vulcanizate determined by this method was 2. 3%，and the recovery rate was 88. 0% to 104. 1%. The method was easy to operate，and the results were accurate and reliable. |
