庚酸合成路线

庚酸上下游产品

庚酸制备

1、先由庚烯-1和合成气经羰基化制得庚醛,再经空气氧化得到庚酸。先将1-庚烯合成气(一氧化碳+氢气)、循环气及催化剂溶液送入羰基化 反应器中,控制温度为94-150℃,压力为1.30MPa;反应产物经减压闪蒸分出醛类,催化剂和重组分可循环使用。然后将醛类送入氧化的应器, 在混合过渡金属催化剂系统中,在低于0.69MPa压力下,在空气中进行氧化。其中醛几乎达到全部转化,因此,不需分离和循环。所得产物经脱 除所含微量催化剂后,送入双塔精馏系统,在第一塔中脱除重组分(可作燃料),塔顶物料送入第二塔,即得成品支链酸。

2、由1-己烯用合成气(CO+H2)羰基化而成庚醛,再经空气氧化而成。

3. 烟草:OR,44,49;BU,56;FC,BU,OR,18;BU,OR,26;FC,40。

4.制法:

于装有搅拌器、温度计的反应瓶中,加入水2.8L,慢慢加入浓硫酸350mL,冰水浴冷却至15℃,加入正庚醛(2)342g(3mol)。剧烈搅拌下,分批加入高锰酸钾340g(2.15mol),每次约加入15g,控制反应液不超过20℃,约2h加完。加完后继续搅拌反应0.5h。通入二氧化硫气体直至澄清(也可加入适量的亚刘酸氢钠)。分出油状物,水洗一次。减压蒸馏。前馏分分出水后重新蒸馏。收集159~161℃/13.3kPa的馏分,得正庚酸(1)300g,收率77%,纯度95%~97%。注:①将纯度95%的正庚酸溶于适量的氢氧化钠水溶液中,水蒸气蒸馏,直至馏出物中无油状物。剩余物冷却,用盐酸酸化,分出正庚酸,而后减压蒸馏,收集155~157℃/10.6KPa的馏分,可得到纯度接近100%的正庚酸,收率85%~90%。
