ABSTRACT:
Described is a process for easily preparing an .alpha.-bromo,.omega.-chloroalkane which is high in purity represented by the formula: Br(CH.sub.2).sub.n Cl in which n stands for an integer of 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.degree. C. of 20 or larger, for example, N,N-dimethylformamide, N,N-dimethylacetamide or N,N-dimethylimidazolidinone is preferred.
