摘要
以尿素为基本原料 ,经过热解缩合法合成了异氰脲酸 ,后者依次与环氧氯丙烷、十八酸和 2 ,4 二羟基二苯甲酮进行反应 ,合成了高分子量的紫外线吸收剂UV -10 0 9,产品总收率达 76%。
A new high relative molecular mass ultravioet absorber UV-1009 was prepared by using urea as starting material, which is coverted into iso cyanuric acid via pyrosis condensation. The latter reacts with epichlorohydrin, octadecylic acid and 2,4 dihydroxybenzophenone in turn. The total yield of product is over 76%.
