NPA (normal propyl alcohol) in chemistry
N-Propyl Alcohol normal propanol (also known as n-propanol, 1-propanol, Propan-1-l) is a primary alcohol with a molecular formula of CH3(CH2)2OH. It is a colourless, transparent liquid that has a typical sharp musty odour that is comparable with the smell of rubbing alcohol.
Physical Properties of NPA (normal propyl alcohol)
The physical properties of NPA alcohol include its boiling point, melting point, and density. n-Propanol has a boiling point of approximately 97°C and a melting point of -127°C. Its density is slightly less than water, at 0.804 g/mL (at 20°C). Furthermore, n-propanol is miscible with water in any proportion and is readily soluble in alcohols, ethers, and many other organic solvents.
Chemical Properties of NPA (normal propyl alcohol)
NPA alcohol is a typical alcohol compound and exhibits the general properties of alcohols. For example, it can undergo esterification reactions with acids to form the corresponding ester compounds. In addition, n-propanol can undergo oxidation and dehydrogenation reactions. It is important to note that n-propanol has a certain degree of toxicity and is irritating to the skin and eyes; therefore, protective measures must be taken when handling it.
Safety Characteristics
NPA (normal propyl alcohol) is a flammable liquid with a medium flash point of approximately 15°C. It is highly flammable and prone to combustion and explosion upon contact with open flames or high heat. Store away from heat sources and in a well-ventilated, dry place. Skin contact may cause mild irritation; for prolonged handling, it is recommended to wear protective gloves and goggles and avoid inhaling vapors.
