The chemical enriches the soil with beneficial lime and, upon coming into contact with water, begins to break down, releasing nitrogen into the soil by way of ammonia. It is also used in the explosives and pyrotechnics industries. First isolated in 1782, cyanide is a compound composed of carbon triple bonded to nitrogen (CN). Calcium cyanide also known as black cyanide, is an inorganic compound with the formula Ca(CN) 2.It is a white solid, although it is rarely observed in pure form. Very toxic to aquatic life with long lasting effects. Acute (short-term) inhalation exposure may cause gastritis,rhinitis, pharyngitis, laryngitis, and tracheobronchitis. Sodium amide is obtained by the reaction of ammonia with Na at 400°C. Web site owner: She also volunteers at an animal shelter and operates a home bakery. 2. See 50 Federal Register 13456 (April 4, 1985). USA.gov. On ex- posure to the air, calcium cyanide slowly reacts with the moisture of the atmosphere and gives off hydrocyanic-acid gas. New Window. Acute exposure to the chemical can lead to an upset stomach, bronchitis, laryngitis; flushing in the face, upper body and arms, low blood pressure and fast heart rate. It was first synthesized in 1898 by Adolph Frank and Nikodem Caro (Frank-Caro process). The chemical is applied directly to the soil, where it breaks down into ingredients that are beneficial to plan growth. EYES: First check the victim for contact lenses and remove if present. According to the U.S. Environmental Protection Agency, commercially available calcium cyanamide preparations appear as a lumpy powder that is dark gray to black in color. May react rapidly with oxidizing agents. Belongs to the Following Reactive Group(s), Self-contained breathing apparatus and full protective clothing, including rubber footwear. The main use of calcium cyanamide is in agriculture as a fertilizer. Calcium is necessary for many normal functions of the body, especially bone formation and maintenance. If calcium cyanamide comes into contact with your skin or eyes, the product must be washed thoroughly away to prevent negative health effects.
