通过原位还原-缩合配位法合成了β-(2,4-二氨基苯氧基)乙醇-水杨醛Schiff碱锌(Ⅱ)配合物,并用FTIR、1H NMR、TG-DTG和DSC方法分析了产物的结构。结果表明,在实验条件下,锌(Ⅱ)配合物的收率为53.1%,且β-(2,4-二硝基苯氧基)乙醇(2,4-DNPE)还原产物β-(2,4-二氨基苯氧基)乙醇(2,4-DAPE)的氧化被有效抑制;TG-DTG及DSC分析表明,产物在温度超过114℃时即出现明显分解,在630℃时基本分解完全;在N2氛围中,锌(Ⅱ)配合物完全分解后的残余物为原样品质量的27.81%,结合FTIR和1H NMR的分析结果,说明锌(Ⅱ)配合物为目的物。
The Zn (Ⅱ) complex of Schiff base of β - (2,4-diaminophenoxy) ethanol-salicylaldehyde was synthesized by in-situ reduction-condensation coordination method and characterized by FTIR, 1H NMR, TG-DTG and DSC The structure of the product was analyzed. The results showed that the yield of zinc (Ⅱ) complex was 53.1% under the experimental conditions, and the reduction product of β- (2,4-dinitrophenoxy) ethanol (2,4-DNPE) , 4-diaminophenoxy) ethanol (2,4-DAPE) was effectively inhibited. TG-DTG and DSC analysis showed that the product decomposed obviously when the temperature was above 114 ℃ and completely decomposed at 630 ℃ ; In N2 atmosphere, the residue of zinc (Ⅱ) complex completely decomposed was 27.81% of the original sample mass. Combined with the results of FTIR and 1H NMR, the zinc (Ⅱ) complex was the target.
