摘要:用溴化—脱溴化氢一步法制备二乙炔基苯,研究碱、催化剂、反应温度及反应时间等因素对产率的影响。结果表明,以聚乙二醇-400为相转移催化剂,二乙炔基苯的产率达68.6%。用气相色谱、红外光谱、核磁共振和质谱对产物进行了分析表征。
Diethynylbenzene was prepared by the reaction of bromination-dehydrobromination. The effects of different alkali, catalyst, reaction temperature and reaction time on its yield were investigated. It was found that the higher yield could be obtained by using alkali NaOH and phase transfer catalyst poly(ethylene glycol)-400. The diethynylbenzene was characterized by gas chromatography, FT-IR, 1H-NMR and MS.
