| 摘 要： | 以三聚氯氰为原料,通过格氏反应、Friedel-Craft反应合成了2-氯-4,6-二(4-联苯基)-1,3,5-均三嗪(Ⅳ);化合物Ⅳ在碱性条件下与溴代烷反应合成了3种2,4-二(4-联苯基)-6-(2-羟基-4-烷氧基苯基)-1,3,5-均三嗪(Ⅴ1～3)。用FTIR、MS、1HNMR对化合物Ⅴ1～3结构进行了确证,用TGA、UV-Vis对化合物Ⅴ1～3的热稳定性、紫外吸收及光稳定性进行了测定。结果表明,与市售商品化紫外线吸收剂UV-1577相比,化合物Ⅴ1～3的T5(质量损失5%时的温度)提高了40～60℃;具有更宽的吸收范围和更高的最大摩尔吸收系数(εmax)。化合物Ⅴ1～3的εmax分别为:79 448.28 L/(mol.cm)(λmax=318.5 nm),80 873.51 L/(mol.cm)(λmax=319 nm),76 774.7 L/(mol.cm)(λmax=319 nm)。 |

| Abstract: | Cyanuric chloride was used as raw material to synthesize 2-chloro-4,6-bisbiphenyl-1,3,5-triazine(Ⅳ) successfully via Grignard reaction and Friedel-Craft reaction.Three 2,4-bisbiphenyl-6-(2-hydroxyl-4-alkoxyl)-1,3,5-triazine compounds(Ⅴ1～3) were synthesized by compound Ⅳ and bromoalkane in the presence of K2CO3.The structures of compounds Ⅴ1～3 were characterized by FTIR,MS and 1HNMR.Thermal stability,ultraviolet absorption and light stability of compounds Ⅴ1～3 were tested by TGA and UV-Vis.T5 of compounds Ⅴ1～3 was raised 40～60 ℃related to UV-1577.Maximum molar absorption coefficient(εmax) of compounds Ⅴ1～3 was 79 448.28 L/(mol·cm)(λmax=318.5 nm),80 873.51 L/(mol·cm)(λmax=319 nm),76 774.7 L/(mol·cm)(λmax=319 nm) respectively. |
