Separation of o‐ and p‐chloronitrobenzene by solvent extraction. I

Phase equilibrium data have been determined for o ‐ and p ‐chloronitrobenzene in systems containing methanol (both anhydrous and containing 10% v/v water) and n‐heptane and have been used to evaluate the possibility of using distribution between these solvents as a means of separating a mixture of the isomers.
