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.

本论文以1-溴丙烷为溶剂，将引发剂溶于其中，加热到引发剂开始分解时再通入丙烯和HBr，使二者溶解于1-溴丙烷中，在液相中进行反应，实现丙烯"一步法"合成高纯1-溴丙烷利用NaBr与硫酸在氢溴酸存在下反应制备HBr气体，以作为合成1-溴丙烷的原料。
