一种含吡咯-2-亚甲醛结构的席夫碱铁配合物吸波材料及制备方法
Abstract:
本发明公开了一种含吡咯‑2‑亚甲醛结构的席夫碱铁盐吸波材料制备方法，制备共分为两步，第一步以吡咯‑2‑亚甲醛与1,3,5‑三嗪‑2,4,6‑三胺为原料，在无水乙醇中，以乙酸为催化剂，加热回流一定时间，可制备得到N,N'(吡咯‑2‑亚甲醛)缩1,3,5‑三嗪‑2,4,6‑三胺席夫碱化合物；第二步N,N'(吡咯‑2‑亚甲醛)缩1,3,5‑三嗪‑2,4,6‑三胺席夫碱和三氯化铁为原料，在无水乙醇中，加热回流一定时间，可制备得到N,N'(吡咯‑2‑亚甲醛)缩1,3,5‑三嗪‑2,4,6‑三胺席夫碱铁盐。上述席夫碱及其铁盐均具有良好的吸波性能。
Abstract(English):

The invention discloses a preparation method of a Schiff base iron salt wave absorbing material containing a pyrrole-2-aldehyde structure. The method comprises the following steps: 1, heating and refluxing pyrrole-2-aldehyde and 1,3,5-triazine-2,4,6-triamine which are used as raw materials in anhydrous ethanol for a certain time by adopting acetic acid as a catalyst in order to prepare an N,N'-(pyrrole-2-aldehyde)-1,3,5-triazine-2,4,6-triamine Schiff base compound; and 2, heating and refluxing the N,N'-(pyrrole-2-aldehyde)-1,3,5-triazine-2,4,6-triamine Schiff base and ferric trichloride which are used as raw materials in anhydrous ethanol for a certain time to prepare the N,N'-(pyrrole-2-aldehyde)-1,3,5-triazine-2,4,6-triamine Schiff base iron salt. The Schiff base and its iron salt have good wave absorbing property.
