As study on lophophora Cu(Ⅱ) complexes of Schiff base derived from p-hydroxybenzaldehyde and p-aminobenzoic acid

利用超音速气流低热固相法合成了对羟基苯甲醛缩对氨基苯甲酸Schiff碱配体,再以该配体和乙酸铜为原料,通过添加十二烷基硫酸钠(SDS)的方式制备出了晶形规整的仙人球型配合物,利用元素分析和红外等现代测试手段确定了配合物的结构组成。扫描电镜(SEM)研究表明,配合物为规整的仙人球型,颗粒平均尺寸为2.5μm,初步探讨了仙人球型配合物的形成机理;并进一步探讨了反应物计量比、温度、时间对配合物产率的影响,得到了合成产物的最佳工艺条件:反应物计量比1∶1,反应时间2 h,温度50℃,配合物产率达83.48%。

Schiff base derived from p-hydroxybenzaldehyde and p-aminobenzoic acid was prepared by solid-state reaction at supersonic speed airflow and low-heating. Lophophora shape Cu（ Ⅱ ） complexes was prepared from the Schiff base and copper acetate and through adding sodium dodecyl sulfate （SDS）. The structural composition of complexes was confirmed by FTIR and elemental analysis. SEM results showed that the complexes were lophophora shape, and the average size of the product particles was 2.5 μm. The formation mechanism of lophophora shape complexes was studied. Molar ratio, temperature and reaction time affecting the yield of complexes was investigated. The optimized reaction conditions with a yield of 83.48% of the complexes were： molar ratio 1 ： 1, reaction time 2 h, temperature 50 ℃.
