Methanol (CH3OH, CAS 67-56-1) is a clear, colorless, flammable liquid with a specific gravity of about 0.79, a boiling point of 149°F (65°C) and a flash point of about 52°F (11°C). It is toxic if swallowed, inhaled or absorbed through the skin. Methanol is a building block for formaldehyde, acetic acid and olefins, and is used in biodiesel production, windshield washer fluid, fuel blending and as a carbon source for wastewater denitrification. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
