Propanol, also known as 1-propanol, propan-1-ol, 1-propyl alcohol, n-propyl alcohol, or n-propanol, is a primary alcohol with the formula CH3CH2CH2OH.
Contents
Properties
Chemical
Oxidation of 1-propanol with chromic acid yields propionic acid.
Physical
Propanol is a colorless liquid with an alcohol like smell. It is miscible in water and many organic solvents.
Availability
Delete this section if not applicable
Preparation
1-Propanol is manufactured by catalytic hydrogenation of propionaldehyde.
Projects
- Make n-propyl iodide
Handling
Safety
Propanol is thought to be similar to ethanol in its effects on human body, but 2-4 times more potent. However, the toxicity of propanol is comparable to that of methanol (LD50 1870 mg/kg, as compared to 1500 mg/kg of methanol and 7060 mg/kg of ethanol), so it should never be consumed.
Storage
In closed bottles away from any heat source.
Disposal
Propanol can be safely burned.
