Abstract: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%. |
Key words:urea; ultravioet absorber; synthesis |
