| titleOfInvention | Method of preparing aromatic ether bisimides |
| abstract | A method for preparing an aromatic ether bisimide is provided. The mixture obtained from reacting a substituted phthalimide, shown below, with a metal salt of a hydroxy aromatic compound in a non-polar solvent is extracted with about 4% to about 6% by weight aqueous alkali hydroxide solution to remove the reaction's by-products and thus provide substantially pure aromatic ether bisimide. The method is particularly suitable for extracting aromatic ether bisimide by-products from a continuous process preparing aromatic ether bisimide,n n wherein R¹ is hydrogen, an alkyl radical having from 1 to 8 carbon atoms or an aryl radical having from 6 to 13 carbon atoms and X¹ is a nitro or halo radical. |
