摘要
Abstract
Three new s-triazine UV absorbents 2, 4-bis ( 2-hydroxyl-4-alkoxyl) phenyl-6-( 4-biphenyl)-l ,3, 5-triazine containing different alkoxyls were synthesized from cyanuric chloride by Grignard reaction, Friedel-Craft reaction and etherification reaction. The target compounds were characterized by means of FTIR, 'H NMR and MS. Ultraviolet absorption performances, light stabilities and thermal stabilities of the target compounds were tested. The results showed that ultraviolet absorption performances of the target compounds in the range of 280 - 380 run were stronger than that of the commercialized product 2-(2-hydroxy1-4-heoxyl) phenyl-4,6-diphenyl-l ,3,5-triazine (Dssorb UV-1577). The maximum molar absorption coefficients of the three target compounds are 50 502.05 and 52 363.88 L/( mol ·cm), 45 123.59 and 49 892. 84 L/( mol · cm), and 52 282.02 and 53 291.56 L/(mol · cm), respectively. The target compounds have the similar light stability to Dssorb UV-1577 and their thermal stabilities are higher than that of Dssorb UV-1577.关键词
