The present invention is directed to a method for making a di(aminoaryl)fluorene compound that includes the steps of: (a) reacting a fluorenone compound according structure (I) with excess aminobenzene according to structure (II) wherein: each R1, R2, R3, R4, R12, and R13 is independently a group that is inert in the polymerization of epoxy compounds, and R11 is H or (C1-C6)alkyl, in the presence of an acid catalyst, in a liquid medium comprising an aromatic or substituted aromatic solvent having a boiling point of greater than or equal to 150°C and in the presence of an acid catalyst, in a liquid medium comprising an aromatic or substituted aromatic solvent having a boiling point of greater than or equal to 150°C and from which the di(aminoaryl)fluorene compound is crystallizable, to form a crude product mixture comprising the di(aminoaryl)fluorene compound, (b) crystallizing di(aminoaryl)fluorene compound in the product mixture, and (c) separating the product mixture into crystallized di(aminoaryl)fluorene compound and a filtrate.
本发明涉及一种制备二(氨基芳基)芴化合物的方法,包括以下步骤:(a)在酸催化剂存在下,将结构式(I)的芴酮化合物与过量的结构式(II)的氨基苯反应,其中:每个R1、R2、R3、R4、R12和R13独立地是在环氧化合物聚合中惰性的基团,而R11为H或(C1-C6)烷基,反应在具有沸点大于或等于150℃的芳香或取代芳香溶剂中,从中可以结晶出二(氨基芳基)芴化合物,形成包含二(氨基芳基)芴化合物的粗产品混合物;(b)结晶粗产品混合物中的二(氨基芳基)芴化合物;(c)将产品混合物分离为结晶的二(氨基芳基)芴化合物和过滤液。
