2-己醇制备

1.制法：

于装有搅拌器、滴液漏斗、温度计的反应瓶中，加入醋酸汞31.9g(0.1mol),水100mL，搅拌使醋酸汞溶解，加入100mL四氢呋喃，立即生成橙黄色。搅拌15min后，加入1-己烯(2)8.5g（0.1mol），室温搅拌反应1h，以使羟汞化完全。剧烈搅拌下加入3mol/L的氢氧化钠溶液100mL，滴加由硼氢化钠1.9g(0.05mol)溶于100mL3mol/L的氢氧化钠配成的溶液，滴加速度控制反应液温度25℃左右。必要时可用水浴冷却。反应中迅速生成元素汞。室温剧烈搅拌反应3h，于分液漏斗中放置过夜。分出汞(19.25g,96%)和水，保留有机层。水层用氯化钠饱和，乙醚提取(3mL×2),合并有机层，减压蒸出溶剂，当出现两相时停止蒸馏。加入50mL乙醚和20mL水。分出乙醚层，水洗四次，无水磷酸钙干燥。先蒸出乙醚，剩余物继续蒸馏，收集136～140℃的馏分，得2-己醇（1）6.9g，收率68%。
