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.
一种制备通式为##STR1##的2-(4'-羟基芳基)-2-(4'-氨基芳基)-丙烷的方法,其中R代表氢或卤素原子或烷基、芳基、硝基、腈基、酰基、酰氧基或氨基基团,R.sup.1代表具有1至4个碳原子的氢原子或烷基,R.sup.2和R.sup.3独立地表示氢或卤素原子、硝基或具有1至4个碳原子的烷基,所述方法包括在0.00001到0.008摩尔的酸催化剂存在下,将(A)至少一种选择自由基为##STR2##的异丙基酚衍生物和该异丙基酚衍生物的双-到十二烯体与(B)通式为##STR3##的芳香胺反应,其中R.sup.1,R.sup.2和R.sup.3如定义,在存在或缺乏酚类溶剂的情况下。
