正戊烷制备

1.戊烷可由天然气或石油催化裂解、热分解过程中获得。由于精制程度不同，常含有Ｃ５烃的异构体、甲基环戊烷等沸点相近的烃类以及不饱和化合物、水分、含硫化合物等杂质。精制时，不饱和化合物用硫酸洗涤除去，可用氯化钙、无水硫酸钠、五氧化二磷或金属钠等脱水剂脱水，再进行蒸馏。也可用分子筛脱水。

2.由顺丁烯二酸酐加氢，或由呋喃在镍催化剂存在下氢化制得。

3.以抽提C5为原料，经加氢后精馏分离，可得到正戊烷。或者以天然气凝析油为原料，经精馏分离可得到正戊烷。还可以以正戊醇为原料，经脱水、加氢、精馏制得正戊烷。

4.以工业品正戊烷为原料，先用浓硫酸洗涤至酸层无色，然后用0.02mol／L高锰酸钾的10%硫酸溶液洗涤至烯烃含量合格。再依次用0.02mol／L高锰酸钾的10%氢氧化钠水溶液、水洗涤，然后用无水氯化钙干燥，过滤后蒸馏，收集中间馏分，即为纯品。

5.通过2-戊醇和3-戊醇再氢化制得，亦可由2-溴戊烷通过Grignard反应制得。
