Green preparation method of 2,2-bis(4-aminophenyl)hexafluoropropane

The invention relates to the field of fine organic synthesis, in particular to a green preparation method of 2,2-bis(4-aminophenyl)hexafluoropropane. The green preparation method comprises the following steps: (a) carrying out oxidation reaction on 2,2-bis(4-methylphenyl)hexafluoropropane and oxygen in a perfluorinated compound solvent, and conducting separating to obtain 2,2-bis (4-carboxyphenyl)hexafluoropropane; (b) carrying out a reflux reaction on the compound obtained in the step (a) and ammonia gas in an organic solvent to obtain ammonium salt of 2,2-bis(4-carboxylphenyl)hexafluoropropane; (c) mixing the compound obtained in the step (b) with an organic solvent, carrying out heating, and raising a temperature for dehydrating to obtain 2,2-bis(4-formamidophenyl)hexafluoropropane; and (d) carrying out a Hofmann degradation reaction on the compound obtained in the step (c) and sodium hypochlorite in a hydrofluoroether solvent, and carrying out purifying to obtain the 2,2-bis(4-aminophenyl)hexafluoropropane. According to the invention, a selected oxidizing agent is economical and green, and the oxidizing solvent is non-combustible and non-explosive; and a hydrofluoroether solvent is selected for the Hofmann reaction, so high-COD wastewater is reduced, and industrial production is facilitated.
