Acetaldehyde (CH3CHO, CAS 75-07-0) is a colorless, extremely flammable liquid with a sharp, fruity odor. It has a specific gravity of about 0.79, boils at only 68°F (20°C) and has a flash point near -36°F (-38°C). It is used as a chemical intermediate for pyridines, pentaerythritol, peracetic acid and acetate esters, and in small amounts as a flavoring. Bulk acetaldehyde storage needs cool, vented, inerted tanks away from ignition sources. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
Polypropylene is the most economical tank material for Acetaldehyde, rated Excellent. Nylon is also rated Good or better. Avoid PVDF (Kynar®) tanks; PVC, CPVC and PVDF fittings; Buna-N and Viton® gaskets. Rated Fair (contact us before use): HDPE tanks and HDPE fittings.
