紫外线吸收剂Padimate O的合成研究

Study on the Synthesis of Ultraviolet Screen——Padimate O

Padimate O作为一种抗紫外线的吸收剂 ,广泛应用于化妆品及其它透光防日晒工业品中。使用一种含醋酸锌的钛类复合物为催化剂 ,使 4- ( N,N-二甲氨基 )苯甲酸和异辛醇酯化反应合成了目标物。合成方法鲜见有文献报道 。

Padimate O is used widely for sunburn protection and cosmetic ultraviolet sunscreen. It is synthesized from 4 ( N, N dimethylamino) benzoic acid and 2 ethylhex anol, catalyzed by a mixture of Zn Ti compounds. This synthesis method has harly any been reported before, and it is suitable for industrial scale production.
