2-辛酮制备

1.由蓖麻油裂解产物仲辛醇经氧化而成。

2.制法：

于装有搅拌器、温度计、回流冷凝器、滴液漏斗的反应瓶中，加入2-辛醇（2）65g（0.5mol），乙醚200mL，冰水浴冷却。滴加250mL铬酸溶液^①，保持反应温度在25～30℃，约20min加完。而后于室温继续搅拌反应2h。分出乙醚层，水层用乙醚提取（80mL×4），合并乙醚层，依次用饱和碳酸氢钠、饱和氯化钠溶液洗涤，无水硫酸钠干燥。蒸出乙醚。而后常压蒸馏，收集170～172℃的馏分，得到2-辛酮（1）53g，收率81%。铬酸溶液可按如下方法来配制：100g（0.33mol）二水合重铬酸钠溶于300mL水中，慢慢加入73mL硫酸（98%），冷后用水稀释到500mL。

^3.制法：

于装有搅拌器、回流冷凝器的反应瓶中，加入甲酸100mL，辛炔-1（2）7.5g，油浴加热，于100℃搅拌反应直至起始原料基本反应完。反应过程中用气相色谱跟踪反应。反应约6h时气相色谱定量分析表明生成92%的2-辛酮。冷却，二氯甲烷提取，依次用水、碳酸钠溶液、水洗涤，无水硫酸镁干燥。过滤，减压浓缩后蒸馏，收集171～173℃的馏分，得化合物（1）7.42g，收率85%。
