HCN

About Hydrogen Cyanide. Hydrogen Cyanide (a.k.a. HCN, Prussic Acid, Hydrocyanic Acid) is a chemical precursor used in the production of several industrially relevant compounds, from polymers to pharmaceuticals. Hydrogen Cyanide is a volatile, flammable, and highly toxic gas in temperatures above 25 °C. Otherwise, it is a dangerous transparent liquid and its storage and transport are prohibited in certain locations.

Hydrogen Cyanide is directly produced on an industrial scale through two main routes. The direct production of HCN known as the Andrussow process is based on the reaction of ammonia, methane (natural gas), and air over a platinum catalyst. The so-called Blausäure-Methan-Ammoniak (BMA) process, in turn, is based on the reaction of ammonia and methane only. Finally, Hydrogen Cyanide may also be indirectly produced as a by-product of acrylonitrile production involving propylene ammoxidation. It is worth noting that Hydrogen Cyanide plants are necessarily integrated into consumer facilities.

Hydrogen Cyanide Handling. Hydrogen Cyanide has a low boiling point, high toxicity, and instability in the presence of moisture, bases, or other impurities. Materials compatible with HCN are stainless steel, Hastelloy, and Monel. To prevent polymerization, stabilizing agents such as sulfuric acid, phosphoric acid, oxalic or acetic acid, and sulfur dioxide are used. Larger amounts are stored at a maximum temperature of 5 °C and must be permanently recirculated. The color of the liquid should not exceed APHA 20. Storage and handling buildings must be well-ventilated. Due to its toxicity, HCN requires special packaging and transportation regulations. Small quantities of the stabilized acid are transported in metal cylinders with less than 0.55 - 0.60 kg of liquid HCN per 1 L bottle. The water content should not exceed 3 %, and the storage time should be less than one year. Hydrogen cyanide is mainly shipped by rail, respecting applicable transport regulations. Transport in rail cars is only permitted with the approval of the relevant authorities.

Hydrogen Cyanide Production. Currently, HCN is mainly produced directly through the reaction of ammonia, natural gas, and air (Andrussow process) and through the reaction of ammonia and natural gas (BMA process); and as a by-product from the acrylonitrile production through the ammoxidation of propylene. Raw materials and the respective production processes employed in the manufacturing of Hydrogen Cyanide are listed below.

  • Propylene + ammonia (ammoxidation)
  • Formamide (BASF formamide process)
  • Natural gas + ammonia + air (Andrussow process),
  • Natural gas + ammonia (BMA process),
  • Propane/raffinate II + ammonia (Shawinigan electrothermal process)

Hydrogen Cyanide Uses. The uses and applications of Hydrogen Cyanide may vary according to its specification. The main forms of Hydrogen Cyanide are technical grade (96-99.5% purity); 5 and 10% aqueous solutions; 2% USP grade solution; and gas. All grades usually contain a stabilizer to prevent decomposition.
