摘要
以工业废氢溴酸（48％）为原料，在浓硫酸存在下，与正辛醇进行反应合成1-溴辛烷。考察了反应条件对产率的影响，结果表明，比较合适的反应条件为：正丁醇：氢溴酸：浓硫酸（摩尔比）=1：1．15：1．38，反应时间3h，反应温度110～115℃，产率达到99．0％。粗产品经气相色谱分析证明几乎无副产物，产品经IR和折光率进行表征。
1-Bromooctane was synthesized from industrial hydrobromic acid （48%） and n-octanol using concentrated sulfuric acid as catalyst. Various affecting factors were investigated. The optimal condition was as follows：the mole ratio of n-octanol,hydrobromic acid and concentrated sulfuric acid was 1 ： 1.15 ： 1.38, refluxed for 3 h, the reaction temperature was between 110℃ and 115℃, the yield of 1-bromooctane was up to 99.0%. Raw product was analyzed by GC and no by-product was detected. Pure product was characterized by IR and index of refraction.
