UV-531合成工艺研究

Study on Synthetic Process of UV-531

考察了以2,4 二羟基二苯甲酮、正溴辛烷为原料,在碳酸钾存在的条件下,以环己酮为溶剂,一步法直接合成UV 531。通过实验研究,确定了该合成反应的最佳工艺条件,在此工艺条件下,合成UV 531的收率在92%以上。

2Hydroxyl4octoxydiphenylketone is directly synthesized by 2,4dihydroxydiphenylketone and noctyl bromide at the present of K2CO3 as the catalyst and cyclohexanone as solvent. And the process is optimumized. At the optimum condition,the yield of the product is over 92%.
