Unformatted text preview: CHEMICAL FAMILY SUMMARY FSE 305/OSH 305 Name: Date: CHEMICAL FAMILY: Organic Cyanides GENERAL FORMULA: Derivatives with general formula (R-CN) CLASSICAL NAMING CONSIDERATIONS IUPAC NAMING CONSIDERATIONS Classical nomenclature, they end with the suffix In IUPAC nomenclature, these are named nitriles while in classical nomenclature, they ‘cyanide’ end with the suffix ‘cyanide’. WHAT ARE THE GENERAL HAZARDS ASSOCIATED WITH THIS FAMILY? - They are very toxic and very irritating to the human body, causing direct damage to the respiratory tract. - Cyanide is a rapidly acting, potentially deadly chemical that can exist in various forms. - Cyanide can be a colorless gas, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl), or a crystal form such as sodium cyanide (NaCN) or potassium cyanide (KCN). - Hydrogen cyanide (HCN) is a toxic liquid or colorless gas. WHAT ARE THE COMMON USES OR APPLICATIONS OF THIS FAMILY? - They are used in the extraction of metals and as pesticide fumigants. - Hydrogen cyanide (HCN); A toxic liquid or colorless gas. Hydrogen cyanide is found in the smoke of various tobacco products and released by combustion of nitrogen-containing organic materials. REMARKS OR OTHER CONSIDERATIONS Cyanide is released from natural substances in some foods and in certain plants such as cassava, lima beans and almonds. Pits and seeds of common fruits, such as apricots, apples, and peaches, may have substantial amounts of chemicals which are metabolized to cyanide. The edible parts of these plants contain much lower amounts of these chemicals. COMMON USES - In manufacturing, cyanide is used to make paper, textiles, and plastics. - It is present in the chemicals used to develop photographs. - Cyanide salts are used in metallurgy for electroplating, metal cleaning, and removing gold from its ore. - Cyanide gas is used to exterminate pests and vermin in ships and buildings. ...
