    摘要： A preparation process of a bis(3-nitrophenoxy) compound represented by the formula:

    wherein X is a direct bond, divalent hydrocarbon having from 1 to 10 carbon atoms or a divalent group selected from -C(CF₃ )₂-, -CO-, -S-, -SO-, SO₂- or -O-, which comprises reacting 4,4'-bisphenol with m-dinitrobenzene in the presence of an alkali metal carbonate or alkali metal hydrogen carbonate having a particle size of 250 µ m or less while removing generated water from the reaction system during the reaction. In one embodiment of the process, the reaction is carried out while simultaneously adding 4,4'-bisphenol and m-dinitrobenzene to a reaction vessel which was previously charged with the base and an aprotic polar solvent.

    摘要： A diphenylamine with both the phenyl groups being substituted is prepared by reacting a phenol with ammonia in the presence of a hydrogen transfer catalyst and a cyclohexanone; or by converting a portion of the phenol to the cyclohexanone in the presence of a hydrogen transfer catalyst and under hydrogen pressure and then reacting the remaining portion of the phenol with ammonia in the presence of the cyclohexanone so converted and the hydrogen transfer catalyst. The diphenylamine can be obtained very efficiently.
