A process is disclosed for separating nitrated phenolic compounds from other nitrated and unnitrated phenolics by treating a mixture of the phenolics with a metal halide salt. The metal halide salt preferentially forms a complex with one of the phenolics over other related phenolics in the mixture. The preferentially-formed complex of one of the phenolics may then be isolated from the mixture and the complex decomposed to provide a product substantially enriched in, or substantially entirely composed of, one phenolic. The process is particularly suitable for resolving a mixture comprising phenol or cresol from their ortho-nitrated derivatives, or a mixture of two isomeric nitrated phenols or cresols or a mixture of mono- and dinitrated phenols or cresols.
