<p>Described is a process for easily preparing an alpha -bromo, omega -chloroalkane, which is high in purity, represented by the formula: Br(CH2)nCl in which n is an integer of from 4 to 12. The process comprises reacting in an organic solvent an alpha , omega -dichloroalkane with an alpha , omega -dibromoalkane. As the organic solvent, an aprotic nitrogen-containing or sulfur-containing organic solvent having a dielectric constant at 20 DEG C of 20 or larger, for example, N,N-dimethylformamide, N,N-dimethylacetamide or N,N-dimethylimidazolidinone is preferred.</p> |
