摘　　要：本文通过氰基乙酸和醇反应得到中间体氰乙酸酯,再通过Knoevengal缩合和酯交换反应得到终产物2-氰基-3,3-二苯基丙烯酸酯.对所合成的化合物进行了1H NMR、IR等结构表征,并对终产物的紫外线吸收性能进行测试.结果表明这些化合物对中波段紫外线(UVB)具有优良的吸收性能和良好的热稳定性.In this paper, the intermediates of cyanoacetate were prepared by the reaction of cyanoacetic acid with alcohol, then the target compounds were obtainted through the Knoevengal reaction and transesterification. Finally,the compounds synthesized were confirmed by 1H NMR, IR, and the property of them were tested by UV,TG, etc.
