| 中文摘要: |
| 开展了硅胶吸附脱除注射用大豆油氢过氧化物的研究。以过氧化值为评价指标，筛选硅胶种类，优化吸附工艺参数，并对吸附脱除氢过氧化物后的注射用大豆油的其他质量指标进行评价。结果表明，最佳吸附工艺条件为：选用粒度为70~200 μm的进口硅胶，硅胶添加量11％，反应温度60 ℃，反应时间1.0 h。在最佳工艺条件下，注射用大豆油的过氧化值、酸价、皂化值、碱性杂质、不皂化物等指标均符合注射用大豆油国家标准。 |
| 英文摘要: |
| Silica gel was used as adsorbent to remove hydroperoxide from soybean oil for injection. The peroxide value was used as an evaluation index to select the silica gel type and optimize the adsorption process parameters. At the same time, other quality indicators of soybean oil for injection after adsorption by silica gel were evaluated. The optimal adsorption parameters were obtained as follows: using imported silica gel with particle size of 70-200 μm as adsorbent, silica gel dosage 11%, reaction temperature 60 ℃ and reaction time 1.0 h. Under the optimal conditions, the peroxide value, acid value, saponification value, alkaline impurities and unsaponifiable matter of soybean oil for injection after adsorption could meet the national standard of soybean oil for injection. |
