Reactivity Profile
ACETALDEHYDE AMMONIA reacts with strong oxidizing agents and halogens. Attacks copper, aluminum, zinc and their alloys. Reacts with mercury and silver oxides to form shock-sensitive compounds [Handling Chemicals Safely 1980. p. 139]. Readily decomposes into acetaldehyde and ammonia when heated, causing the hazards of those substances [Lewis].

Applications
DescriptionAcetaldehyde ammonia is a white crystalline solid and very soluble in water. It is used to make other chemicals and vulcanise rubber. On long exposure to air, acetaldehyde ammonia oxidises, hardens, and turns yellow or brown in colour and reacts exothermically with water to evolve gaseous ammonia. Acetaldehyde ammonia reacts with strong oxidising agents and halogens, and when heated, it readily decomposes into acetaldehyde and ammonia. It attacks copper, aluminium, zinc, and their alloys and reacts with mercury and silver oxides to form shock-sensitive compounds.
UsesFor preparing pure acetaldehyde; in organic syntheses.
General DescriptionA white crystalline solid. Melting point 97°C. Boiling point 110°C (with some decomposition). An addition product between acetaldehyde and ammonia. Presents moderate fire and explosion hazard when exposed to heat or flame. Moderately toxic by ingestion and inhalation and a strong irritant. Used to make other chemicals, vulcanize rubber.
