| 中文摘要: |
| 研究苯酚改性α-甲基苯乙烯石油树脂的连续流生产工艺。原料预处理工艺优化：当精馏回流比为3、分子筛类型为4A时，α-甲基苯乙烯的纯度为98.1%，苯酚水分含量为0.06%，产品的色度为4，收率为90.5%。生产工艺参数优化：当三氟化硼乙醚络合物用量为2.0%、反应温度为60 ℃、反应压力为0.3 MPa、物料停留时间为45 min、α-甲基苯乙烯与苯酚的质量比为7∶1、物料流速为150 mL·h-1时，反应转化率为92%，产物相对分子质量分布指数为2.0，软化点波动小，产品综合性能较好。设备选型优化：采用管式反应器结合316L不锈钢材质，在兼顾性能与成本的同时，可实现中试装置连续稳定运行。 |
