In this paper, initiator is dissolved in 1-bromopropane which is solvent. Then the propene and hydrogen bromide that can be dissolved in 1-bromopropane are inlet in l-bromopropane when initiator is decomposing. The reaction occurs in fluid phase and high-purity 1-bromopropane is synthesized by one step method. In this paper, the material HBr is synthesized with NaBr and sulfuric acid at the presence of hydrobromic acid.
