摘　　要：以二苯甲酮为原料经过酰胺化、还原、水解得二苯甲胺盐酸盐,再与水杨醛及其衍生物5-氯水杨醛反应,生成了两种二苯甲胺缩水杨醛类Schiff碱。其中二苯甲胺盐酸盐的酰化最佳反应条件为:回流温度控制在140℃,时间为20h,收率为89%;目标产物总收率均为97%以上,并利用IR、MS、1 H NMR、UV-vis及荧光光谱等方法对产物进行了表征。Aminodiphenylmethane hydrochloride was synthesized from benzophenone by amidation, re- duction and hydrolysis reaction. Then, it further reacted with salicylaldehyde and its derivative, 5- chlorine-salicylaldehyde, respectively to form two kinds of novel Schiff Base Aminodiphenylmethane condensation salicylaldehyde. The optimal acylation reaction conditions were as follows. The yield could be up to 89% when reflux temperature was 140 ℃ and reaction time was 20 h. The total yield of each target product was above 97G. The composition and structure of the products were characterized by means of IR, MS, 1H NMR, UV-Vis, Fluorescence spectroscopy and other methods.
