摘　　要：以5-苯甲酰基-2,4-二羟基苯甲醛为原料,无水硫酸镁为吸收剂,在乙醇溶剂中与不同芳胺缩合得到系列二苯甲酮并席夫碱类化合物,通过1H NMR、13C NMR、IR、MS等对二苯甲酮并席夫碱类化合物进行结构表征,并探究其紫外吸收性能。结果表明:该类化合物能够有效吸收280~360 nm紫外线,吸收范围广,吸收强度强,兼具长波紫外线(UVA)和中波紫外线(UVB)的吸收性能,是一类具有开发前景的紫外线吸收剂。Using 5-benzoyl-2,4-dihydroxybenzaldehyde as raw material and anhydrous magnesium sulfate as absorbent,a series of benzophenone-schiff base compounds were obtained by condensation with different aromatic amines in ethanol solvent.The structures of benzophenone-schiff base compounds were characterized by 1H NMR,13C NMR,IR and MS,and their ultraviolet absorption properties were also explored.The results show that this kind of compounds can effectively absorb the ultraviolet light of 280~360 nm,with a wide absorption range and strong absorption intensity.It has both the absorption properties of long-wave ultraviolet UVA and medium-wave ultraviolet UVB,and is a promising ultraviolet absorber.
