EXTRACTIVE RECOVERY OF NITROSOPHENOL AND AMINOPHENOL AND THEIR DERIVATIVES BY C-3-C-4 ALCOHOLS

Isomers of propyl and butyl alcohols were used for extractive recovery of nitroso- and aminophenols, their alkyl anal nitro derivatives, sal icylidene-2-aminophenol, and nitro and nitroso derivaties of resorcino l in the presence of a salting out agent. Distribution coefficients an d degree of extraction of 12 nitrogen-containing phenols were establis hed, as well as the relationship between the extraction characteristic s and the structure of the compound extracted. Efficient extraction sy stems are recommended that allow nearly complete recovery of nitrogen- containing phenols from aqueous media.
