紫外线吸收剂1,4-双(β-二羰基甲氧基乙烯基)苯的合成研究

Study on a UV absorber 1,4-bis(β-dicarbmethoxyvinyl)benzene

对苯二甲醛与丙二酸二甲酯反应生成紫外线吸收剂1,4-双(β-二羰基甲氧基乙烯基)苯,通过对一系列反应条件的考察,得出合成的最佳工艺条件。

A new UV absorber—1,4-bis（β-dicarbmethoxyvinyl）benzene was synthesized by reaction of p-phthalaldehyde with dimethyl malonate,and a series of reaction factors are investigated and the best condition of synthetizing the new light stabilizer was showed.
