Butyl Amine (n-butylamine, C4H9NH2, CAS 109-73-9) is a colorless, highly flammable liquid with a strong ammonia-like odor, a specific gravity of about 0.74, a boiling point near 172°F (78°C) and a flash point near 10°F (-12°C). It is corrosive to skin and eyes. Butylamine is used to make rubber vulcanization accelerators, pesticides, pharmaceuticals, dyes and emulsifiers. Store in grounded, vented tanks away from acids and oxidizers. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
Nylon is the most economical tank material for Butyl Amine, rated Excellent. Polypropylene is also rated Good or better. Avoid PVDF (Kynar®) tanks; PVC and PVDF fittings; Viton® gaskets. Rated Fair (contact us before use): HDPE tanks and HDPE fittings.
