摘要 采用酸洗精制工艺对丁二烯聚合用循环溶剂油进行净化处理后,油品碘值≤0.03 g/100 g油,染色值≤0.005。将该溶剂油用于丁二烯聚合,产品质量和产量均有提高。酸洗工艺条件(质量比):油酸比100/6,酸碱比5/2。 Recycled solvent oil for butadiene polymerization was treated by using acid purification process.After purifing, the iodine number of the recovered solvent process oil ≤ 0.03 g/100 g oil,and the dye number≤ 0.005. When this recovered oil was used in the butadiene polymerization, both the quality and the output of the product were increased.The conditions of the acid purification process were: oil/acid ( mass ratio ) = 100/6, acid/base = 5/2.
