Abstract

Substituted fluorobenzenes which are produced in aprotic, polar solvents or in mixtures which contain such solvents can be obtained by extracting the substituted fluorobenzenes from the solvents or solvent mixtures with aliphatic extracting agents and then seaprating the extracting agents from the substituted fluorobenzenes.
