摘　　要：以三聚氯氰、乙醇和间苯二酚为主要原料,分两步合成得到一种均三嗪类紫外线吸收剂2,4-二乙氧基-6-(2’,4’-二羟基苯基)-1,3,5-三嗪,并对该物质以及其中间体2,4-二乙氧基-6-氯-1,3,5-三嗪进行了表征。在优化合成工艺的基础上,试验确定其中间体合成优化工艺为:反应温度35℃,反应时间24 h,以碳酸氢钠为缚酸剂,其用量为原料三聚氯氰摩尔量的3倍;最终产物紫外线吸收剂的合成优化工艺为:反应温度110℃、反应时间8 h、相对于中间体2,4-二乙氧基-6-氯-1,3,5-三嗪催化剂无水三氯化铝用量为0.9 mol。A s-type ultraviolet absorber 2,4-diethoxyl-6-（2,4-dihydroxylphenyl）-1,3,5-triazine has been synthesized from cyanuric chloride,ethanol and resorcinol through two-step reaction,this ultraviolet absorber and its intermediate 2,4-diethoxyl-6-chloro-1,3,5-triazine have been characterized by FT-IR,1H-NMR,Mass Spectrum and ultraviolet-absorb spectrum in this article.The synthesizing processes of these two compounds have also been discussed in this article,and it is found that in the best synthesis process for the intermediate： the reaction uses 50mL ethanol and 5mL water as the solvent system with 3 equivalents of sodium bicarbonate as the hydrogen chloride scavenger compared to 0.1 mol cyanuric chloride,the reaction temperature is controlled at 35℃,and lasted for 24 hours;as for the ultraviolet absorber,the best synthesis process is 0.9 equivalent of anhydrous aluminium trichloride compared to intermediate 2,4-diethoxyl-6-chloro-1,3,5-triazine as catalyst,and the reaction temperature is controlled at 110℃,the reaction time is controlled for 8 hours.
