抽余C_9合成石油树脂的研究

Experimental Study on Synthesizing Petroleum Resin with Raffinate C_9

以三氟化硼乙醚络合物为催化剂,对抽余C_9聚合制备石油树脂进行了实验研究。探讨了催化剂添加量、反应温度、反应时间等因素对聚合反应的影响,得到了软化点大于100℃,收率大于80%的树脂样品。

Experimental study was made on preparation of petroleum resin through polymerization of raffinate C9 with boron trifluoride ether complex as catalyst. The optimal process conditions for polymerization reaction were concluded： catalyst dosage 2%, reaction temperature 110 ～ 120℃ and reaction time 4h. After reaction, solvent need to be added for water scrubbing. The resin gained through reaction under optimal process conditions has a softening point of over 100℃ and yield of over 80% .
