Propyl Alcohol (n-propanol, C3H7OH, CAS 71-23-8) is a clear, flammable alcohol with a specific gravity of about 0.80, a boiling point of 207°F (97°C) and a flash point near 59°F (15°C). Its isomer, isopropyl alcohol, is often called propyl alcohol in everyday use. Both are used as solvents for printing inks, coatings, cleaners and disinfectants, and as chemical intermediates. Propyl alcohol tanks need grounding and fire protection. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the most economical tank material for Propyl Alcohol, rated Excellent. Polypropylene and PVDF (Kynar®) are also rated Good or better. Avoid nylon tanks.
