PRODUCTION OF BIS(3-AMINOPHENOXY) COMPOUND

摘要

PURPOSE:To obtain the high-purity title compound in good yield and suppressed subsidiary production of an azo compound without filtration leak of a catalyst by subjecting a bis(3-nitrophenoxy) compound to catalytic reduction while adding the above- mentioned compound to a reactor in which a Raney nickel catalyst and reaction solvent are previously charged. CONSTITUTION:When a compound expressed by formula I [X is 1-10C bivalent hydrocarbon group, C(CF3)2, CO, S, SO, SO2, O or single bond] is subjected to catalytic reduction, the reaction is carried out by using a Raney nickel catalyst, while adding said compound I to a reactor in which the reaction solvent and the catalyst are previously charged. The temperature of the reaction is controlled at 50-100 deg.C and of the pressure at ordinary pressure to a slight pressurization of about 1000mmH2O by an addition rate of said compound I corresponding to the reaction rate to provide the compound expressed by formula II in suppressed subsidiary production of an azo compound which is difficult to remove. The addition of the compound expressed by formula I is preferably carried out for >=45hr in the case of reaction temperature at 50 deg.C and for >=2hr in the case of reaction temperature at 85 deg.C. The compound expressed by formula II is important as a monomer component for heat resistant high polymer.
