Anhydrous definition

Anhydrous means without water, where the ammonia is stored as a gas at high pressure, while “aqueous” means the ammonia is diluted to some degree with water, Typically, aqueous ammonia is specified at concentrations of 19.5%, 25%, or 29% pure ammonia in water

Anhydrous means that the compound no longer has water molecules associated with it.

Anhydrous means without water. Consequently, when anhydrous ammonia comes into contact with water, it rapidly combines with the moisture and forms ammonia hydroxide. When injected into the soil, the liquid ammonia expands into a gas and readily combines with soil moisture. Similarly, the liquid or gas that contacts body tissue—especially the eyes, skin, and respiratory tract—will remove the water and cause dehydration, cell destruction, and severe chemical burns. A concentration of anhydrous ammonia vapor of 134 parts per million (PPM) will cause most people to experience dryness and irritation of the nose, throat, and eyes. At 700 PPM, it can cause coughing and severe eye irritation, which may lead to partial or total loss of sight if untreated. A concentration of 1,700 PPM can cause serious lung damage and, if untreated, death. After a few seconds of exposure at 2,000 PPM, burns and blisters can result. At 5,000 PPM, death by suffocation can occur within minutes. (Source: “Using Agricultural Anhydrous Ammonia Safely”, Robert D. Grisso, David Morgan, and Rollin D.
