摘要
以对溴甲苯、三聚氯氰、间苯二酚和溴代正丁烷为原料,通过格氏反应、傅克反应、醚化反应,合成了一种新型的三嗪类紫外线吸收剂;采用正交试验法讨论了各步反应温度、反应时间以及原料摩尔比等对合成产率的影响,并对合成产物进行了表征。结果表明:根据红外光谱,合成产物与目标产物相符,确定产物为2,4-二(2'-羟基-4'-丁氧基苯基)-6-(4″-甲基苯基)-1,3,5三嗪;该合成反应工艺简单,合成产率高,在较佳反应条件下,格氏反应、傅克反应、醚化反应的合成产率分别为80.60%,81.24%,73.58%;该紫外线吸收剂对UVA和UVB都有很强的吸收能力,最大吸收波长分别为345,275 nm。
A novel triazine ultraviolet absorbent was synthesized by using bromotoluene, cyanuric chloride, resorcinol and 1 -butyl bromide as raw material via Grignard reaction, Friedel-Crafts reaction and etherification reaction. The effects of the reaction temperature, reaction time and mole ratio of feedstocks on the synthesis yield were discussed by orthogonal experiment. The synthesis product was characterized. The results showed that the synthesis product was proved to be the target product, 2,4-bis （2′-hydroxyl-4′-butoxylphenyl）-6-（4′-methylphenyl）-1,3,5 triazine, by infrared spectrametry; the synthesis process was of simple process and high synthesis yield; the synthesis yields of Grignard reaction, Friedel-Crafts reaction and etherification reaction were 80.60%, 81.24% and 73.58% , respectively, under rational process conditions; and this ultraviolet absorbent possessed high UVA and UVB absorption capacity and the maximum absorption wavelength was 345 and 275 nm for UVA and UVB, respectively.
