GENERAL DESCRIPTION

HEXAMETHYLENETETRAMINE (HEXAMINE) is a white crystalline powder with slight amine odor. Specific gravity is 1.27  at 25C . HEXAMINE is soluble in water, alcohol, and chloroform, but insoluble in ether.  Formaldehyde and ammonia yield methenamine, or hexamethylenetetramine, which is used as a urinary antiseptic. Nitration of methenamine gives the explosive cyclonite, or RDX. Formaldehyde and acetaldehyde react with Hexamine in the presence of calcium hydroxide to give pentaerythritol, the tetranitrate of which is the explosive PETN.  HEXAMINE is also useful in adhesives, coatings, and sealing compounds. In medicine, it is an antibacterial agent. It is used as a dye fixative and in the preservation of hides. It is used in vulcanizing rubber and as an anti-corrosive agent in steel. It is used in the detection of metals and in the absorption of poisonous gases. It stabilizes lubricating and insulating oils. It is sometimes burned in camping stoves, because it burns without smoke.
