Study On The Synthesis And Application Of New Schiff Base And Intermediate

Chapter1:Introduces the definition of Schiff base physicochemical properties, research on dynamic Schiff base application and the present study focus on the direction of domestic and abroad, summarizes the synthesis method of Schiff base as well as the present situation, defined as a Schiff base intermediate hydrazide and application research.Chapter2:Schiff base is aldehyde and ketone and amine (RNH2) generated by dehydration condensation, the direct synthesis method,3-amino-9-ethyl carbazole as raw material respectively with anisaldehyde and B two formaldehyde, reaction for1-2hours at room temperature, to obtain the product N,N’-9-ethyl-carbazole-3-methoxy-benzoyl amine and N,N’-9,9’-3,3’-ethyl carbazole ethylenediamine, studied the N,N’-9-ethyl-carbazole-3-methoxy-benzylamine and N, N’-9,9’-3,3’-ethyl carbazole ethylenediamine UV-Vis absorption spectra and fluorescence spectra, N determination of-9-,N ’ethyl-carbazole-3-methoxy-benzylamine and N,N’-9,9’-3,3’-ethyl carbazole ethylenediamine melting range, respectively is262-263℃and168℃～169℃. Study of N,N’-9-ethyl-carbazole-3-methoxy-benzylamine and N,N’-9,9’-3,3’-ethyl carbazole ethylenediamine UV-Vis absorption spectra and fluorescence spectra, N, two main violet N’-9-ethyl-carbazole-3-methoxy-benzylamine. The absorption peak at338nm and432nm, fluorescence emission peak position of452nm. N,N’-9,9’-3,3’-ethyl carbazole-two main UV absorption peak at294nm and419nm, fluorescence emission peak position in448nm. Compared with raw3-amino-9-ethyl carbazole and products of N,N’-9-ethyl-carbazole-3-methoxy-benzylamine by UV and fluorescence spectra were studied, using water as the medium, storage time and pH on N,N’-9-ethyl-carbazole-3-methoxy-benzylamine and N,N’-9,9’-3,3 ’-ethyl carbazole ethylenediamine UV-Vis absorption effect.Chapter3:Study of N, N’-9-ethyl-carbazole-3-methoxy-benzylamine and N,N’-9,9’-3,3’-ethyl carbazole ethylenediamine and metal ions in the UV-Vis absorption spectra and fluorescence spectra, and N,N’-9-ethyl-carbazole-3-methoxy-benzylamine and metal ion color and fade. Show that the N,N’-9-ethyl-carbazole-3-methoxy-benzylamine has selective adsorption on Al3+, in neutral and acidic conditions, metal ions are almost not with N,N’-9,9’-3,3’-ethyl carbazole ethylenediamine effect. In alkaline conditions, only Cr3+and N,N’-9,9’-3,3’-ethyl carbazole ethylenediamine had obvious effects, under alkaline conditions,N,N’-9,9’-3,3’-ethyl carbazole and Cr3+adsorption selectivity of ethylenediamine. N,N’-9-ethyl-carbazole-3-showing different colors of the complexes of methoxy-benzylamine and metal ion formation, and in certain conditions may fade, N,N’-9-ethyl-carbazole-3-methoxy-benzylamine-Al3+complexes with yellow and water fast fading,N,N’-9-ethyl-carbazole-3-methoxy-benzylamine-Ag+complex and N,N’-9-ethyl-carbazole-3-methoxy-benzylamine-Cu2+complexes were green and green, gradually faded in the acidic condition. N,N’-9-ethyl-carbazole-3-of colored complexes with methoxy-benzylamine and Al3+, Ag+, Cu2+formation may be applied to environmental protection ink fade.Chapter4:Naphthalene two benzoyl hydrazine was prepared by UV, explore the naphthalene two formylhydrazine visible absorption spectra and fluorescence spectroscopy (ND) and bovine serum albumin (BSA) combined with spectral characteristic function. The results showed that the fluorescence quenching of ND BSA produced, and is mainly a static quenching, the results of the study show that between ND and BSA effect is mainly manifested as hydrogen bonds and van der Waals force; synchronous fluorescence spectra showed that ND changed the conformation of BSA.
