Synthesis And Characterization Of The S-triazine Derivatives With Phenoxy, Bi-naphthoxy And Azo-phenoxy

In this paper, cyanuric chloride which structure containing three chlorine atoms was used as the main raw material for the provision of s-triazine ring.With the different reactivities of the three chlorine atoms in cyanuric chloride, a series of new s-triazine ring compounds were received by the step-wise reaction through the controlling of the temperature.The structure of these compounds were characterized by Elemental analysis, IR,1H NMR and other research methods,also the solubility, thermal stability properties were studied. It can be summarized as follows.1. With cyanuric chloride and p-nitrophenol as the raw materials,2,4,6-3-p-nitrophenoxy-1,3,5-triazine was prepared by controlling of reaction temperature in acetone and water. Three different methods were used for nitro reduction to obtain 2,4,6--aminophenoxy-1,3,5-triazine. With elemental analysis,1H-NMR, IR,TG characterization the products obtained,2,4,6-3-p-nitrophenoxy-1,3,5-triazine shows good thermal stability which the initial decomposition temperature was at 430℃. Pd/C hydrazine catalyst system shows a good result in three kinds of reduction methods.2. With cyanuric chloride and 1,1'-BINOL as the raw materials, NaOH as base, cetyltrimethyl ammonium bromide as phase transfer catalyst, poly 2-chloro-4-1,1'-bi naphthyloxy-1,3,5-triazine were prepared through interfacial polymerization. Its structure was characterized using UV, IR,1H-NMR, RF, GPC. Also by atomic force microscope(AFM), the surface of the polymer film was observed.3. PCCAB was abtained by the reaction of cyanuric chloride and 4,4'-hydroxyazobenzene using interfacial polymerization. DIATOB was got by the reaction of 2-Anilino-4,6-dicholoride-1,3,5-traizine and 4,4'-hydroxyazobenzene at 40℃in the solvent of acetone and water. FTIR,1HNMR, TG, DSC, UV were used to characterize the structures. And the opticl response property of DIATOB was studied by UV-Vis. Also the solubility of the two products were studied, PCCAB won't dissolve even in DMF, but DIATOB can be dissolved in most kinds of solvent.
