| titleOfInvention | Process for producing polyaminopolyphenylmethane using mixed solid acid catalyst system |
| abstract | A method for preparing an aromatic polyamine, comprising: (1) preparing a non-aqueous aminal solution; (2) contacting the non-aqueous aminal solution with an acidic siliceous catalyst to form a benzylamine intermediate; (3) contacting an benzylamine intermediate with an ion exchange resin catalyst based on a styrene-divinylbenzene copolymer to form an aromatic polyamine reaction mixture containing a polyaminopolyphenylmethane product; and (4) an aromatic Recovering the polyaminopolyphenylmethane product from the polyamine reaction mixture. This process, which can be practiced continuously, has a high yield of 4,4′-methylenedianiline, reduced impurities, catalyst life when compared to many conventional processes for preparing polyaminopolyphenylmethane. Resulting in an increase in the cost and thus an improvement in the economic aspect. |
