Preparation of 1-Propanol:
It is a major constituent of fusel oil, a by-product formed from certain amino acids when potatoes or grains are fermented to produce ethanol. 
It is manufactured by catalytic hydrogenation of propionaldehyde. The propionaldehyde is itself 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.
H2C=CH2 + CO + H2 → CH3CH2CH=O
CH3CH2CH=O + H2 → CH3CH2CH2OH
A traditional laboratory preparation of 1-propanol involves treating n-propyl iodide with moist Ag2O.

Safety Information of 1-Propanol:
The 1-Propanol is extremely irritating when contact with eyes and may cause burns.The vapors irritate nose and throat. In high concentrations, it may cause nausea, dizziness, headache, and stupor.So we should keep container tightly closed and away from heat. When you use it ,wear eye/face protection and avoid contact with skin. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
