摘 要:以苯甲醛、苯胺为起始原料,经过无水乙醇纯化得到纯化的二苯基甲酰胺(亚胺)。此亚胺又称为席夫碱,深黄色固体,易溶于乙醇溶剂。该亚胺在Se/CO/H2O的体系中,以DMF为溶剂,于常压下,在温度为90℃的条件下搅拌5个小时,然后停止通气,搅拌、静置、氧化,经过后处理过程得到所需产物二硒醚。此反应的优点是在常压下进行,反应条件温和,反应工艺简单,操作简便、安全,后处理简单,成本低,对环境友好,符合绿色化学的要求,反应选择性高且产率较高。用TLC以及红外光谱对该产物进行分析,结果表明:生成产物时原料爬板很完全,红外特征峰非常明显。关键词:亚胺;硒;二硒醚;Se/CO/H2O体系7558
Synthesis of Imine And Imine Produce Diselenides
Abstract:Imine was prepared by benzaideeehyde,aniline as the starting material which purified through ethanol to afford pure diphenyl acetamide(Imine), the Imine called, the yellow solid. The product was characterized by IR,TLC;The surface properties of the product also was determined carefully, The outcome revealed that the product had good emulsifying and foaming capacity with stable foam, which indicated the product had good surfactant.
Key Words:Imine; Selenium; diselenides ; Se/CO/H2O system
