摘要： 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.
