CONTINUOUS SEPARATION OF AN ISOMER MIXTURE CONTAINING ORTHO-, META- AND PARADICHLOROBENZENEHERMANN WOLZWILHELM MULLER
Thekey difference between ortho nitrophenol and para nitrophenolis that ortho nitrophenol consists of a -OH group and a -NO2 group at 1stand 2ndpositions of the ring structure, whereas para nitrophenol consists of a -OH group and a -NO2 group attached to the 1stand 4thpositions of the ring...
