SECTOR OVERVIEW 1.1 Sector Definition, Facility Names and Locations Hydrogen cyanide (HCN) is produced in the United States by 10 manufacturers through the Inorganic (Andrussow and Blausaure-Methan-Ammoniak (BMA)) process. Table 1.1 presents the names and locations of the HCN producers1. Figure 1.1 shows the geographical location of the facilities on a U.S. map. The numbers on the map correspond to the facility numbers in Table 1.1.

(Rohm and Haas) PO Box 672 Deer Park, TX 77536 This listing determination is for the inorganic HCN manufacturing process. HCN production as a byproduct of acrylonitrile manufacturing (also referred to as the Sohio process) will not be addressed, since this type of production is directly linked to organic chemicals manufacturing and has already been subjected to a listing determination (K011 - Bottom stream from the wastewater stripper in the production of acrylonitrile; K013 - Bottom stream from the acetonitrile column in the production of acrylonitrile; and K014 - Bottoms from the acetonitrile purification column in the production of acrylonitrile). The facilities that produce HCN utilizing the Sohio process were sent RCRA §3007 questionnaires to confirm that they manufacture HCN utilizing an organic process. 1.2 Products, Product Usage and Markets Hydrogen cyanide is a highly volatile liquid which produces poisonous vapors at room temperature, has a molecular formula of HCN, and has a molecular weight of 27.03 grams/mol (g/mol). Hydrogen cyanide melts at -13.2 degrees Celsius (o C) and boils at just above 25 o C. HCN is also known as: hydrocyanic acid, prussic acid, and formonitrile. It is a colorless, poisonous, low viscosity liquid having an odor characteristic of almonds. The production of HCN has the following uses: adiponitrile (for nylon 6/6), 41%; acetone cyanohydrin (for methyl methacrylate), 32%; sodium cyanide, 14%; methionine, 4%; chelating agents, 3%; miscellaneous, including cyanuric chloride and nitrilotriacetic acid and salts, 6%.2 2 ChemExpo Home Page, www.chemexpo.com/news/PROFILE981123.cfm Inorganic Hydrogen Cyanide Listing Background Document 2 August 2000 Figure 1.1 Geographical Distribution of Inorganic Hydrogen Cyanide Producers 1 ì ò ô ï í ó ð õ î ñ Inorganic Listing Determination Inorganic Hydrogen Cyanide Listing Background Document 3 August 2000 1 See Table 1.1 for facility name and location. The historical market for HCN has shown a growth of approximately 3 percent per year in the period spanning the years 1988-1997. Future growth of the market from the present time until the year 2002 is expected to continue at the rate of approximately 2 percent per year. Market demand for this product was approximately 1.44 billion pounds in 1998. 3 1.3 Production
