Abstract: front page image
(EN)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.
(FR)La présente invention concerne un procédé de purification d'un 2-aryl -3,3-bis (hydroxyaryle) phtalimidine comprenant le chauffage d'un mélange de réaction comprenant un composé de phénolphtaléine et une arylamine primaire en présence d'un catalyseur acide pour former un mélange de réaction comprenant un 2-aryl -3,3-bis (hydroxyaryle) phtalimidine; tremper le mélange de réaction avec une solution alcaline aqueuse pour former un mélange réactionnel refroidi; extraire le mélange réactionnel refroidi avec un composé aminoaryle pour former une couche organique et une couche aqueuse extraite comprenant un 2-aryl -3,3-bis (hydroxyaryl) phtalimidine brut. L'invention concerne en outre des procédés de production d'un polycarbonate, qui consiste à produire le 2-aryl-3,3-bis(hydroxyaryl)phtalimidine, et à polymériser la 2-aryl-3,3-bis(hydroxyaryl)phtalimidine en présence d'une source carbonate.
