1-Propanol is a primary alcohol with the formula CH₃CH₂CH₂OH (sometimes represented as PrOH or n-PrOH). This colorless liquid is also known as propan-1-ol, 1-propyl alcohol, n-propyl alcohol, and n-propanol. It is an isomer of 2-propanol (propan-2-ol, isopropyl alcohol, isopropanol). It is formed naturally in small amounts during many fermentation processes and used as a solvent in the pharmaceutical industry mainly for resins and cellulose esters.

Product Description

1-Propanol shows the normal reactions of a primary alcohol. Thus it can be converted to alkyl halides; for example red phosphorus and iodine produce n-propyl iodide in 80% yield, while PCl₃ with catalytic ZnCl₂ gives n-propyl chloride. Reaction with acetic acid in the presence of an H₂SO₄ catalyst under Fischer esterification conditions gives propyl acetate, while refluxing propanol overnight with formic acid alone can produce propyl formate in 65% yield. Oxidation of 1-propanol with Na₂Cr₂O₇ and H₂SO₄ gives only a 36% yield of propionaldehyde, and therefore for this type of reaction higher yielding methods using PCC or the Swern oxidation are recommended. Oxidation with chromic acid yields propionic acid.
