    • A process for preparing 2-(4'-hydroxyaryl)-2-(4'-aminoaryl)-propanes of the general formula ##STR1## wherein R represents a hydrogen or halogen atom or an alkyl, aryl, nitro, nitrile, acyl, acyloxy or amino group, R.sup.1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and R.sup.2 and R.sup.3, independently from each other, represent a hydrogen or halogen atom, a nitro group or an alkyl group having 1 to 4 carbon atoms,which comprises reacting (A) at least one isopropenyl phenol compound selected from the group consisting of isopropenyl phenol derivatives of the general formula ##STR2## wherein R is as defined, and di- to eicosa-mers of said isopropenyl phenol derivatives with (B) an aromatic amine of the general formula ##STR3## wherein R.sup.1 , R.sup.2 and R.sup.3 are as defined, in the presence of 0.00001 to 0.008 mole, per mole of said isopropenylphenol compound (A) calculated as a monomer, of a acid catalyst and in the presence or absence of a phenolic solvent.
    • 制备通式为(III)的2-(4'-羟基芳基)-2-(4'-氨基芳基) - 丙烷的方法,其中R表示氢或卤素原子或烷基,芳基,硝基,腈 ,酰基,酰氧基或氨基,R 1表示氢原子或碳原子数1〜4的烷基,R 2和R 3彼此独立地表示氢或卤素原子,硝基或具有1个 包括使(A)至少一种选自下列通式的异丙烯基苯酚衍生物(I)中的R定义的异丙烯基苯酚化合物与(A)至少一种异丙烯基苯酚化合物的反应,和 所述异丙烯基苯酚衍生物与(B)通式为其中R 1,R 2和R 3如所定义的芳族胺在0.00001至0.008摩尔存在下,每摩尔所述异丙烯基苯酚化合物(A)计算得到的 作为单体,由酸催化剂和酚类溶剂存在或不存在。
