    摘要： A process for production of 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane which comprises reacting phenol with 3,3,5-trimethylcyclohexanone in the presence of an acid catalyst, adding an aqueous solution of an alkali to the resulting reaction mixture to neutralize it, removing a water phase from the thus neutralized reaction mixture, cooling the resulting oil phase to crystallize phenol adduct crystals of 1, 1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane while obtaining a primary crystallization filtrate, wherein the primary crystallization filtrate is heated to a temperature of 150-250°C in the presence of an alkali catalyst in an inert gas atmosphere under a reduced pressure to thermally decompose 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane in the primary crystallization filtrate.

    摘要： A process for producing an aminophenol, which comprises

    (A) a step of reacting a dihydric phenol with an aminating reagent in the liquid state under heat in the presence of water and a water-soluble catalyst,
    (B) a step of removing the unreacted aminating reagent from the reaction mixture, and then precipitating the crude aminophenol from the reaction mixture from which the aminating reagent has been removed, thereby to obtain a crystallization mixture containing the crude aminophenol.
    (C) a step of separating the crystallization mixture into crystals of the crude aminophenol and the reaction mother liquor containing the catalyst,
    (D) a step of circulating part or the whole of the reaction mother liquor to the aminating step, and
    (E) a step of washing the crude aminophenol crystals with a washing liquor to obtain the washed crude aminophenol crystals and the washing mother liquor, and thereafter separating the aminophenol from the washed crude aminophenol crystals and purifying it.
