METHOD FOR EXTRACTIVELY CONCENTRATING ANILINE FROM AQUEOUS SOLUTIONS Russian patent published in 1998 - IPC

Abstract RU 2106177 C1

FIELD: environmental control; monitoring of residual aniline content in purified effluents from enterprises engaged in production of aniline dyes. SUBSTANCE: aniline is extracted from industrial aqueous solutions containing, as salting-out agent, ammonium sulfate in concentration 1.0-3.0 mole/l using trioctylaminoxide solutions in toluene. Further monitoring of aniline content in aqueous solutions may be continued photometrically or chromatographically. EFFECT: high-sensitivity method for environmental monitoring. 1 tbl
