  Disclosed herein is a method for producing a 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. The method comprises forming a reaction mixture comprising at least one substituted or unsubstituted phenolphthalein compound, at least one substituted or unsubstituted primary hydrocarbyl amine, and an acid catalyst; and heating the reaction mixture to form 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. An adduct of the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine is formed either by using an excess of the primary hydrocarbyl amine in the first heating step, or by isolating crude 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine after the heating step and then reacting with a further amount of the primary hydrocarbyl amine. The 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine has a formula: where R 1 is selected from the group consisting of a hydrogen and a hydrocarbyl group, and R 2 is selected from the group consisting of a hydrogen, a hydrocarbyl group, and a halogen.

  A method for preparing a metal salt of a hydroxy-substituted aromatic compound is described. The method comprises contacting in an aqueous medium at least one hydroxy-substituted aromatic compound with a base comprising a metal cation to provide a mixture comprising water and a metal salt of said hydroxy-substituted aromatic compound. The aqueous metal salt is then contacted with a substantially water-immiscible solvent at a temperature greater than the boiling point of water at the prevailing pressure to provide a slurry comprising the metal salt of the hydroxy-substituted aromatic compound and a vapor stream comprising the water-immiscible solvent and water. The components of the vapor stream are separated using a vapor handling system comprising a partial reflux condenser to provide a water-rich component and a water immiscible solvent-rich component.
