3. Key Chemical Characteristics

Unique Properties

1-Propanol is a primary alcohol with a hydroxyl group attached to the first carbon atom. It exhibits typical alcohol properties, including the ability to form esters, ethers, and other derivatives.

Reactivity

Oxidation: Oxidizes to form propanal, propanoic acid, and eventually carbon dioxide and water
Esterification: Reacts with carboxylic acids to form propyl esters (e.g., propyl acetate)
Dehydration: Dehydrates to form propylene when heated with concentrated sulfuric acid
Halogenation: Reacts with halogens to form propyl halides

Hazardous Properties

Flammability: Highly flammable liquid with a flash point of 15°C
Toxicity: LD50 1870 mg/kg (rat, oral)
Irritation: Causes eye and skin irritation
