摘要 用格氏试剂偶联法合成了4个有代表性的三嗪型紫外线吸收剂:2,4-双(2,4-二羟基苯基)-6-(4-甲氧基苯基)-1,3,5-三嗪、2,4-双(2,4-二羟基苯基)-6-苯基-1,3,5-三嗪、2-(2,4-二羟基苯基)-4,6-二苯基-1,3,5-三嗪和2,4,6-三(2,4-二羟基苯基)-1,3,5-三嗪,测定了它们的紫外光谱。其中,2,4-双(2,4-二羟基苯基)-6-(4-甲氧基苯基)-1,3,5-三嗪在UVB和UVA都有较强吸收,εmax=36000L/(mol.cm)(λmax=313nm),εmax=36333L/(mol.cm)(λmax=344nm),是其中最好的紫外线吸收剂。 By Grignard reagent coupling, four s-triazine compounds were synthesized, namely 2,4-bis (2, 4-dihydroxyphenyl )-6-( 4-methoxyphenyl )-1,3, 5-triazine, 2,4-bis (2, 4-dihydmxyphenyl )-6- phenyl-1,3,5-triazine, 2- ( 2,4-dihydroxyphenyl ) -4,6-diphenyl-1,3,5 -triazine and 2,4,6-tri ( 2,4- dihydroxyphenyl)-1, 3, 5-triazine, and their ultraviolet spectra were measured. 2, 4-Bis (2, 4- dihydroxyphenyl)-6-(4-methoxyphenyl)-1,3,5-triazine is the best UV absorber in four compounds. [εmax =36 000 L/(mol ·cm) (λmax =313 nm]) ,εmax =36 333 L/(mol·cm) (λmax =344 nm) ].
