Latest Patents

Alok Pal holds a patent for "Continuous methods of manufacture of 2-aryl-3,3-BIS(4-hydroxyaryl)phthalimidines, and polymers derived therefrom." This patent describes a continuous method for the manufacture of a 2-aryl-3,3-bis(hydroxyaryl)phthalimidine. The process involves continuously heating an anhydride with a phenol in the presence of a catalyst and a first co-catalyst. This results in a first reaction mixture comprising a phenolphthalein compound. The method further includes precipitating the phenolphthalein compound, combining a primary arylamine with an acid catalyst and a second co-catalyst to form a second reaction mixture, and adding the phenolphthalein compound to this mixture. The continuous heating of the second reaction mixture leads to a third reaction mixture comprising a crude phthalimidine, which is then treated to remove aminophenol and purify the phthalimidine.
