N-Propyle Acetate (NPA)

Normal propyl acetate (also known as n-propyl acetate or 1-propyl acetate) is an organic compound with a molecular formula of C5H10O2. It is commonly used as a solvent in coatings and printing inks. This product is a clear, colourless liquid that has a distinguishable acetate odour. This product is highly flammable with a flash point of 14° C and a flammability rating of 3. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters) but has only slight miscibility in water.

Production

The most common method for chemically manufacturing normal propyl acetate is through the esterification of 1-propanol and acetic acid which are heated in the presence of a strong acid.

Storage and distribution

A chemical wholesaler would have a bulk petrochemical storage facility to regulate this product. Storage is normally in a cool, dry and well ventilated facility away from oxidising agents. Normal propyl acetate should be kept out of direct sunlight, heat and open flames. Solvents such as normal propyl acetate should be stored in drummed containers such as isotanks made of stainless steel, aluminium or carbon steel.
