| 中文摘要: |
| 在糠醛中加入助溶剂（醇类复合溶剂），对纯糠醛减三线浅度一次抽出油进行二次抽提（中试），研究二次抽提的优化条件。结果表明：二次抽提优化条件为助溶剂质量分数 0. 02，抽提温度 55 ℃，剂（糠醛和助溶剂）/油（一次抽出油）质量比 1. 6，停留时间 50 min；在优化条件下制备的二次抽出油芳碳率和收率较大，苯并[a]芘和8种多环芳烃含量较小。助溶剂/糠醛二次抽出油可用作环保型芳烃橡胶油。 |
| 英文摘要: |
| In this paper，two-stage extraction method of pure furfural extraction oil was studied by adding alcohol-based co-solvent，and the extraction parameters were optimized. The results showed that the optimal conditions were as follows：the mass fraction of the co-solvent was 0. 02，the extraction temperature was 55 ℃，the mass ratio of the extraction agent（furfural and co-solvent） and oil（primary oil from first stage extraction ） was 1. 6 and the residence time was 50 minutes. The contents of benzo[a]pyrene and 8 kinds of polycyclic aromatic hydrocarbons（PAHs） in the product were relatively low，and the yield and aromatic content were quite high. The two stage extraction oil of furfural refining with co-solvent could be used as environmentally-friendly aromatic rubber oil. |
