水杨醛缩4-氨基安替比林与Zn(II),Ni(II),Co(II)配合物的合成和表征

以水杨醛、4-氨基安替比林和醋酸盐为原料,在酸性条件下,以乙醇为溶剂,合成了水杨醛缩4-氨基安替比林希夫碱及其配合物。考察了反应时间、温度、原料配比对该合成的影响。结果表明,反应的最佳条件为:水杨醛∶4-氨基安替比林∶醋酸盐(摩尔比)=1∶1∶1,在80℃条件下反应5 h,产率可达80%。通过红外和紫外光谱进行表征,研究了他们的性质。

Synthesis and characterization of salicylaldehyde-4-aminoantipyrine and its complexs of zinc(II),nickel(II) and cobalt(II)

Salicylaldehyde-4-aminoantipyrine(HL) and its co mp lexs of zinc(II),nickel(II) and cobalt(II) was synthesized by using salicylaldeh yde,4-aminoantipyrine and acetate as main materials and under the condition of acid and ethanol as solvent.After testing the effect of mixture ratio,temperatur e and time on reaction carefully,the result shows that the optimum condition ar e as follows:the mole ratio of salicylaldehyde,4-aminoantipyrine to acetate is 1∶1∶1,the reaction time is 5 h at 80℃.The rate of producti on can amount to 80%.The HL and its complexes are characterized by means of IR a nd UV spectra.
