Method of separating 2-nitrosophenol isomer from admixture with 4- nitrosophenol isomer

摘要

Disclosed is a method for selectively separating 2- nitrosophenol from an isomeric mixture containing 2-nitrosophenol and 4- nitrosophenol by contacting the mixture with an organic solvent so as to preferentially dissolve the 2-nitrosophenol from the mixture.
