Improvement of synthesis of 8–hydroxyquioline aluminum and its aging

FEI Jinbo,TIAN Xike,ZHAO Kexiong,PI Zhenbang(School of Material Science and Chemical Engineering,China University of Geoscience,Wuhan 430074)  
Compared with the traditional method,an improved process was developed to synthesize 8–hydroxyquioline aluminum(AlQ3) by chemical deposition in nitrogen atmosphere.The acidity of solution and reaction time influenced the yield of AlQ3 strongly.The purity and characteristics of the organic material were investigated with a combination of high performance liquid chromatogram(HPLC),Fourier transformation infrared absorption(FT—IR) spectrum and fluorescence spectrum(FL).At pH value 6.5,and reaction time 120 min,the yield and the purity of AlQ3 were 92.7% and 92.5%,respectively.The aging process of as–synthesized AlQ3 was researched with FT–IR and the aging mechanism was discussed.
