二芳基酮的合成及光敏性能

Synthsis and Photocuring Properties of Phenylarylone

在路易斯酸催化剂的催化下，芳香族化合物与苯甲酰氯在一定的温度下反应合成五种不对称二芳基酮类化合物，将合成的二芳基酮类化合物与一定量的胺类化合物混合构成新型光敏剂．这些光敏剂能有效的引发丙烯酸酯类化合物和其齐聚物聚合固化,其引发速度快于二本甲酮与一定量的胺类经合物混合构成的光敏剂。

Five phenyl aryl keton compounds are synthezed by aromatic compound reactionwith benzoy chloride in proper tempriture in catelyst of lewis acid. New Photoinitiator are prepared by mixing these con,pounds with amines. They can result in curing of acrylate, Their efficiencies of initiation are better than photoinitiator dipheyl ketone
