Procedimiento

The reaction liquid was found by gas chromatography (GC) analysis to contain 39.8% of the target compound, 3,3′-bis(1-hydroxy-1-trifluoromethyl-2,2,2-trifluoroethyl)-4,4′-oxydianiline, 5.4% of 3-(1-hydroxy-1-trifluoromethyl-2,2,2-trifluoroethyl)-4,4′-oxydianiline, and 53.0% of the total of various imines produced by the reaction of hexafluoroacetone with the amine moiety of 4,4′-oxydianiline. After adding 50 ml of water to the reaction liquid, stirring was conducted. This mixed liquid was filtered, followed by washing with water and then vacuum drying, thereby obtaining 4.30 g of the target compound, 3,3′-bis(1-hydroxy-1-trifluoromethyl-2,2,2-trifluoroethyl)-4,4′-oxydianiline (yield: 33%; purity: 80.7%).
