Chemical properties
Propionic alcohol 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 propan-1-ol with Na2Cr2O7 and H2SO4 gives 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.
Preparation
Propionic alcohol is manufactured by catalytic hydrogenation of propionaldehyde. Propionaldehyde is produced via the oxo process by hydroformylation of ethylene using carbon monoxide and hydrogen in the presence of a catalyst such as cobalt octacarbonyl or a rhodium complex.

Propionic alcohol is the compound with the hydrogen atom in the propane molecules being replaced by hydroxyl group. Because the hydroxyl group can substitute the hydrogen atoms contained in the carbons in the two terminals of carbon chain or middle carbon, thus generating two isomers, n-propyl alcohol and isopropyl alcohol.
The chemical property of the Propionic alcohol is similar to that of ethanol.
Propionic alcohol is the byproduct during the process of the methanol synthesis from carbon monoxide and hydrogen. At room temperature and normal pressure, it appears as colorless transparent liquid with fragrance odor. In industry, it is prepared through the reaction between ethylene, carbon monoxide and hydrogen under high pressure and cobalt catalysis; alternatively through the hydration of propylene under the action of sulfate or through the catalytic hydrogenation of acetone.
Propionic alcohol is commonly used as a solvent with irritating effect on the eyes and mucosa. Inhalation of propyl alcohol steam can lead to dizziness, headache and vomiting, etc.
The propanols are used mainly as solvents for coatings; in antifreeze compositions and household and personal products; and as chemical intermediates for the production of esters, amines, and other organic derivatives. As a solvent, Propionic alcohol is used principally in printing inks, paint, cosmetics, pesticides, and insecticides.
