A method for the purification of a 2-aryl-3,3-bis(hydroxyaryl)phthalimidine including heating a reaction mixture comprising a phenolphthalein compound and a primary arylamine in the presence of an acid catalyst to form a reaction mixture comprising a 2-aryl-3,3- bis(hydroxyaryl)phthalimidine; quenching the reaction mixture with an aqueous alkali solution to form a quenched reaction mixture; extracting the quenched reaction mixture with an aminoaryl compound to form an organic layer and an extracted aqueous layer comprising a crude 2-aryl-3,3-bis(hydroxyaryl)phthalimidine is provided. Methods for the manufacture of a polycarbonate, including manufacturing the 2-aryl-3,3-bis(hydroxyaryl)phthalimidine, and polymerizing the 2-aryl-3,3-bis(hydroxyaryl)phthalimidine in the presence of a carbonate source are provided.
提供了一种用于纯化2-芳基-3,3-双(羟基芳基)邻苯二酰亚胺的方法,包括在酸催化剂存在下加热反应混合物,该混合物包括邻苯二酚化合物和一种主要芳胺,以形成含有2-芳基-3,3-双(羟基芳基)邻苯二酰亚胺的反应混合物;用含水碱溶液淬灭反应混合物,形成淬灭后的反应混合物;用氨基芳基化合物萃取淬灭后的反应混合物,形成有机层和提取的含有粗2-芳基-3,3-双(羟基芳基)邻苯二酰亚胺的水层。还提供了一种聚碳酸酯的制备方法,包括制备2-芳基-3,3-双(羟基芳基)邻苯二酰亚胺,并在碳酸酯源存在下聚合2-芳基-3,3-双(羟基芳基)邻苯二酰亚胺。
