pyrocatechol usage and synthesis |
chemical properties | off-white powder |
general description | solid; white; odorless. sinks and mixes with water. |
air & water reactions | turns brown on exposure to air and light, especially when moist. water soluble. aqueous solutions soon turn brown on exposure to air and light. |
reactivity profile | poisonous gases may be produced when heated. pyrocatechol may form toxic fumes at high temperatures. [uscg, 1999]. pyrocatechol can react with acid chlorides, acid anhydrides, bases and oxidizing agents. pyrocatechol reacts violently on contact with concentrated nitric acid. pyrocatechol acts as a reducing agent . |
health hazard | dust: irritating to eyes, nose and throat. if inhaled will cause coughing or difficult breathing. solid: will burn skin and eyes. harmful if swallowed. |
fire hazard | combustible. poisonous gases may be produced when heated. may form toxic fumes at high temperatures. |
