METHOD OF SIMULTANEOUS SYNTHESIS OF ORTHO- AND PARA-BROMOANILINES Russian patent published in 1998 - IPC

Abstract RU 2109729 C1

FIELD: organic chemistry. SUBSTANCE: invention relates to a method of synthesis of aromatic amines, i.e. a method of synthesis and isolation of products synthesized by nitration of bromobenzene, pure para-bromonitrobenzene obtained by crystallization and reduction of remained isomer mixture followed by separation of obtained mixture of para- and ortho-bromoanilines by distillation with steam. EFFECT: improved method of synthesis.
