| titleOfInvention | Production of aryl imidodicarboxylate |
| abstract | PURPOSE: To readily obtain the titled compound useful as a raw material for polymerizing polyesters, etc., in high yield and purity at a low cost in a short time, by reacting a specific imidodicarboxylic acid with an aromatic monohydroxy compound under specific condition while heating. n CONSTITUTION: An imidodicarboxylic acid, expressed by the formula (n is 2W12, more preferably 2, 6 or 12, much more preferably 6) and readily obtained by reacting trimellitic acid anhydride with the corresponding alkylenediamine is reacted with an aromatic monohydroxy compound, e.g. phenol, etc., in a molar amount of ≥2 times based on the above-mentioned dicarboxylic acid at 200W320°C, preferably 210W310°C, preferably in an inert gas atmosphere, e.g. N 2 , etc., under normal or higher pressure for 30minW20hr while heating to afford the aimed compound while removing the generated water to the outside of the reaction system. A small amount of a catalyst of a compound of Sn, Ti, Sb, etc., e.g. Sn(OCOCH 2 ) 2 , Ti(OBu) 4 , etc., is preferably added to improve the rate of reaction. n COPYRIGHT: (C)1987,JPO&Japio |
