Synthetic method 4,4 ' -bis (3 -aminophenoxy) diphenyl sulfone

The invention discloses a synthetic method of 4,4 '- bis (3 -aminophenoxy) diphenyl sulphone, which comprises 1, 3 -dinitrobenzene and 4,4 -dihydroxydiphenyl sulfone through nucleophilic substitution reaction in the presence of an alkaline catalyst to generate 4,4' - bis (3 - 3 - '-nitrophenoxy) diphenyl sulfone through catalytic hydrogenation reaction to form bis 3 - (and 4,4-aminophenoxy) diphenyl sulphone. 4,4' . The raw material 1,3 - dinitrobenzene adopted by the synthetic method is only one third of the price of the meta-aminophenol, so that the production cost is greatly reduced. In addition, the reaction temperature is 110 - 120 °C, and compared with the prior art, the reaction temperature is mild and the energy consumption is lower. The synthesis method disclosed by the invention not only is high in reaction yield, but also can obtain higher product purity by adopting n-heptane for recrystallization, the product color is white, the content of metal ions is low, and the synthesis method is suitable for industrial production.

Bis(3-aminophenoxy) aromatics and method of preparing the same

Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons and certain substituted derivatives thereof by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitrophenoxy) derivatives and derivatives obtained are successively reduced to afford bis-(3-aminophenoxy)derivatives. This is a new method for reacting the dihydroxy-derivatives with m-dinitrobenzene, and hence can prepare novel bis(3-aminophenoxy) derivatives such as 4,4'-bis(3-amino-phenoxy)biphenyl, 1-[4-(3-aminophenoxy)phenyl]-1,3,3-trimethyl-6-(3-aminophenoxy)indan, 6,6'-bis(3-aminophenoxy)3,3,3',3'-tetramethyl-1,1'spirobiindan, and methyl substituted 2,2'-bis[4-(3-aminophenoxy)phenyl]propane.
