CAS NO.64-18-6
| Formic acid Usage And Synthesis |
| Chemical Properties | Clear, colorless liquid |
| General Description | A colorless liquid with a pungent odor. Flash point 156°F. Density 10.2 lb / gal. Corrosive to metals and tissue. |
| Air & Water Reactions | Fumes in air. Soluble in water with release of heat. |
| Reactivity Profile | Formic acid reacts exothmerically with all bases, both organic (for example, the amines) and inorganic. Reacts with active metals to form gaseous hydrogen and a metal salt. Reacts with cyanide salts to generate gaseous hydrogen cyanide. Reacts with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides to generate flammable or toxic gases. Reacts with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reacts with carbonates and bicarbonates to generate carbon dioxide but still heat. Can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. May initiate polymerization reactions or catalyze other chemical reactions. A mixture with furfuryl alcohol exploded [Chem. Eng. News 18:72(1940)]. |
| Health Hazard | Liquid causes skin and eye burns. Vapors are irritating and painful to breath. Vapor exposure may cause nausea and vomiting. |
| Fire Hazard | Special Hazards of Combustion Products: Toxic vapor generated in fires |
