制备

1.存在于直馏汽油、铂重整抽余油或湿性天然气中，含量1%～15%。目前，工业生产主要是从铂重整装置的抽余油（含己烷11%～13%）中分离，用精馏法除去轻重组分后，得到含正己烷60%～80%的馏分。采用双塔连续精馏，再经0501型催化剂加氢，除去苯等不饱和烃，得到合格产品。美国还采用吸附分离法制备正己烷。

2.以正己烷为原料（正己烷含量为90%～95%），经过精密精馏制得高纯正己烷。

3.主要采用抽余油分离法。将铂重整装置的抽余油 ( 含乙烷1 1%~1 3%)精馏分离,除去轻重组分后,得正己烷,纯度为6 0%~8 0%,再以6 0~1 4 0℃的馏分为原料 ( 含正己烷1 1%~1 3%) ,采用两塔连续分离,除轻、重组分后,得含正己烷为6 0%~8 0%的馏分,最后经过0 5 0 1催化剂加氢,除去苯等不饱和烃而得正己烷。
