用于制备新型重金属处理剂的含溴和酰胺基单体的合成与表征

Synthesis and characterization of 3,5-dibromo-N-(1-phenylethyl) benzamide

近年来,在土壤污染的众多来源中,重金属污染高居首位。且多呈现出隐蔽性、滞后性、积累性和难可逆性,给生态环境和食品安全带来了严重的威胁,同时,也是污染防治和修复工作的一道难题。多孔材料的吸附性对于重金属处理有很大应用价值。本实验合成了一种含有两个溴原子和一个酰胺基团的单体,其特点是:两个溴原子可与炔类化合物进行偶联反应生成多孔材料,同时,酰胺基团可与金属形成配合物。其化学结构通过核磁共振和傅里叶变换红外进行表征。此单体有望用于重金属处理剂的合成中。

In recent years,heavy metal pollution ranks the first among many sources of soil pollution.Besides,it is hidden,lagged,accumulated and difficult to be reversed,which poses a serious threat to the ecological environment and food safety.Meanwhile,it is also a difficult problem in pollution prevention and restoration.The adsorption of porous materials has great value for the treatment of heavy metals.In this paper,a monomer containing two bromine atoms and an amide group was synthesized.The characters of the monomer are as follows:two bromine atoms can be reacted with acetylene compounds to generate porous material;the amide groups will coordinate with metals.The chemical structures were characterized by 1 H-NMR and FTIR.This new monomer is expected to be used for the synthesis of heavy metal treating agent.
