环己烷中溴值的测定 应用资料 将已知质量的试样溶解于温度维持在0℃~5℃的溶剂中,然后用溴化钾-溴酸钾标准溶液滴定。当溶液中出现的游离溴引起电位滴定仪的电位突然改变时,即表示达到滴定终点。KGM KYOTO ELECTRONICSMANUFACTURING CO.,LTD.TIR-93009enL Application Memo Bromine Number of Cyclohexane 1.Overview According to JIS K 2605-1996 Petroleum distillates and commercial aliphatic olefins -Determination of bromine number -Electrometric method, bromine number of cyclohexane ismeasured by titration with potassium bromide-potassium bromate solution while the testsample dissolved in buffer is maintained at 5℃ or less. The endpoint is determined by theinflexion caused by sharp polar potential change due to free iodine in titration. The brominenumber is calculated from the titration volume of potassium bromide- potassium bromatesolution. 2.
