Synthese
1,5-Dibromopentane (100 Kg), N, N-dimethylformamide (100 Kg), and hexamethylphosphoramide (6.2 Kg) were stirred and mixed, and then heated in an oil bath at 140°C for 4 h. Atmospheric distillation collects the fractions, and the collected fractions are washed twice with 100 Kg brine. The organic liquid is distilled to obtain product 5-Bromo-1-pentene.
