Process for preparing amino-2, 4-dinitroaromatic herbicides |
摘要 |
This invention pertains to a process for producing 2,6 dinitroaniline derivates which are suited as intermediates for herbicides. The process involves the formation of a 1,2,6-trinitro-aromatic isomer and the subsequent nucleophilic displacement of the 1-nitrosubstituent with an amine. The reaction products can easily be separated from other organics by forming an amine salt and extracting with water.
