Patent number: 8163961Abstract: Complexes of 2,3,5,6-tetraaminotoluene with an aromatic diacid are prepared by reaction with a divalent salt of the aromatic diacid while maintaining the pH of the reaction solution between 3 and 10. The resulting complexes are suitable for making high molecular weight polybenzimidazole polymers for high-performance fibers.Type: GrantFiled: February 22, 2010Date of Patent: April 24, 2012Assignee: E. I. du Pont de Nemours and CompanyInventors: Rajiv Dhawan, Joachim C. Ritter

Patent number: 8163955Abstract: An improved process is provided for the preparation of 2,6-diamino-3,5-dinitrotoluene by amination of 2,6-dichloro-3,5-dinitrotoluene. The presence of water unexpectedly results in a highly pure product, free of glycol ether impurities. This product can be used to make highly pure 2,3,5,6-tetraaminotoluene, which in turn can be used to make high molecular weight polybenzimidazoles for high strength fibers.Type: GrantFiled: December 10, 2009Date of Patent: April 24, 2012Assignee: E. I. du Pont de Nemours and CompanyInventors: Rajiv Dhawan, Joachim C. Ritter
