Use

Dry 1-pentanol with anhydrous K2CO3 or CaSO4, filter and fractionally distil it. It has also been treated with 1-2% of sodium and heated at reflux for 15hours to remove water and chlorides. Traces of water can be removed from the near-dry alcohol by refluxing it with a small amount of sodium in the presence of 2-3% n-amyl phthalate or succinate followed by distillation (see ethanol). Small amounts of amyl alcohol have been purified by esterifying with p-hydroxybenzoic acid, recrystallising the ester from CS2, saponifying with ethanolic-KOH, drying with CaSO4 and fractionally distilling [Olivier Recl Trav Chim Pays-Bas 55 1027 1936].
