Two reactive UV absorbents, 2-hydroxy-4(2,3-epoxypropoxy)benzophenone and 4(2,3-epoxypropoxy)acetophenone were synthesized by reaction of hydroxylated aromatic ketone (2,4-dihydroxybenzophenone and 4-acetophenone) and epichlorohydrin under microwave radiation and characterized by IR, NMR, MS and UV-Vis spectra. The optimal reaction condition was as follow: molar ratio of hydroxylated aromatic ketone and epichlorohydrin was 1:3, microwave power was 400 W in sodium hydroxide solution at 90℃ for 15min. The yield was 52.6% and 58.3% under this condition. Comparing with the conventional synthesis process, microwave synthesis can reduce the reaction temperature, greatly shorten the reaction time. The UV absorption properties of aromatic ketone ultraviolet absorbents were improved significantly as the introduction of epoxy propane groups.
