    摘要： A method for purifying a 2-aryl-3,3-bis(hydroxyaryl)phthalimidine comprises contacting a crude 2-aryl-3,3-bis(hydroxyaryl)phthalimidine with a purification agent, removing a 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine compound from the crude 2-aryl-3,3-bis(hydroxyaryl)phthalimidine, and producing a purified 2-aryl-3,3-bis(hydroxyaryl)phthalimidine product comprising less than 200 parts per million of the 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine compound. The purification agent is selected from the group consisting of an acidic material, an organic acid chloride, an organic anhydride, or a combination thereof. The 2-aryl-3-(aminoaryl)-3-(hydroxyaryl)phthalimidine compound has a formula: wherein each R1 is independently selected from a group consisting of a hydrocarbyl radical, a nitro radical, and a halogen atom; “a” is an integer from 0 to 4; and Ar1 and Ar2 are independently at each occurrence an aromatic radical. The purified 2-aryl-3,3-bis(hydroxyaryl)phthalimidines have low color, and are useful for preparing polymers, such as polycarbonates having a low color. The polycarbonates are useful for producing articles.

    摘要： A method for increasing a mean particle size of a 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine is provided. The method comprises forming a mixture comprising a feedstream of the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine, and a solvent composition comprising an organic solvent and water, wherein the organic solvent is capable of at least partially dissolving the 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine and forming an adduct with the 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine. Then the mixture is heated at a temperature and for a time effective to decompose the adduct and form a 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine product having a mean particle size greater than 5 microns. The 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidines with increased particle size are useful for producing polymers.
