摘　　要：报道了在生产 2 -羟基 -4-甲氧基二苯甲酮 -5 -磺酸 (BP-4)的废料中 ,加入络合剂 (M4) ,去掉其中胶质物 ,再加入活性炭 ,从而回收到较纯的 2 -羟基 -4-甲氧基二苯甲酮 (UV -9)的方法 ,并讨论了溶剂、络合剂的用量等实验条件对产品的收率和质量的影响。Hydroxy-4-methoxybenzophenone UV-9 as ultra-violet absorber with relatively high purity was recovered by adding complexing agent M 4 into the waste from the production of 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (BP-4), removing gummy substance, and then adding activated carbon. The effects of laboratory conditions including the amount of solvent and complexing agent on the yield and quality of UV-9 were examined.
