  Methods for synthesizing and purifying 2-aryl-3,3-bis(4-hydroxyaryl)phthalimidine compounds are provided. The method includes heating a reaction mixture including a phenolphthalein, a primary aryl amine, and an acid catalyst to form a phthalimidine; precipitating the phthalimidine from the reaction mixture to provide a crude phthalimidine; providing a solution including the crude phthalimidine, an additive, and at least one solvent; contacting the solution with one or more purification agents to provide a treated solution; precipitating and recovering a phthalimidine adduct from the treated solution; and recovering a purified phthalimidine compound from the adduct.

  本发明提供了合成和纯化 2-芳基-3,3-双(4-羟基芳基)酞脒化合物的方法。该方法包括加热包括酚酞、伯芳基胺和酸催化剂的反应混合物以形成酞脒，从反应混合物中沉淀酞脒以提供粗酞脒，提供包括粗酞脒，添加剂和至少一种溶剂的溶液；将溶液与一种或多种纯化剂接触，以提供处理溶液；从处理溶液中沉淀并回收酞脒加合物；以及从加合物中回收纯化的酞脒化合物。
