正辛烷制备

1.制法：

于装有搅拌器、回流冷凝器、通气导管(伸入瓶底)的反应瓶中，加入锌-汞齐100g(1.53mol),250mL浓盐酸、50mL水，搅拌下加入40g(0.35mol)辛酮-2(2),慢慢通入氯化氢气体。若反应过于剧烈，可暂停通氯化氢气体。2-3h后锌-汞齐大部分反应完，停止通氯化氢，放置过夜。撤去搅拌器等，改为水蒸汽蒸馏装置，进行水蒸气蒸馏，直至镏出液透明为止。分出上层油层，用蒸馏水洗涤二次，无水硫酸钠干燥后分镏，收集124-126℃的馏分，得到辛烷(1)26g,收率58%。

2.制法：

于装有搅拌器、温度计、回流冷凝器的1L反应瓶中，加入除去氧化层的金属钠(切成小块状)23g(1.0mol)。称取用无水硫酸钠干燥过的溴丁烷(2)68.5g(53mL，0.5mol)，先由冷凝器顶端加入5mL，若反应没有进行，可适当加热，直至反应开始(变蓝色)。慢慢搅拌下，再加入5mL溴丁烷。当反应缓慢时再加入5mL溴丁烷，如此直至溴丁烷加完(约1.5h)。加完后放置1～2h。撤去冷凝器，用滴液漏斗滴加50mL(95%)的乙醇，约30min加完，而后于15min内滴加50mL蒸馏水。搅拌下加热回流3h，使未反应的溴丁烷分解。加入500mL水，分出上层粗品辛烷(17～18g)。用等体积的水洗涤，无水硫酸镁干燥，分馏，收集123～126℃的馏分，得辛烷① (1)约15g，收率52%。注：①用Wurtz反应来制备烷烃，其中往往含有少量的不饱和烃。加入约10%体积的浓硫酸并充分挪动，直至酸层无色或仅有很浅的黄色，分出酸层，依次用10%的饱和碳酸钠、水洗涤，无水硫酸镁或无水钠干燥，而后分馏(或减压分馏)，可得到高纯度的烷烃。
