Runa Chemicals Pvt. Ltd. Manufactures Acetic Acid of 463 Degree C Auto-ignition Temperature. Runa Chemicals Pvt. Ltd. Is an ISO 9001:2000 and 14001:2004 certified company. Runa Chemicals Pvt. Ltd. Supplies high purity laboratory chemicals. Acetic Acid of 463 Degree C Auto-ignition Temperature reacts with metals to produces flammable hydrogen gas. Acetic Acid of 463 Degree C Auto-ignition Temperature will ignite on contact with potassium-tert-butoxide. A mixture of ammonium nitrate and acetic acid ignites when warmed, especially if warmed. Acetic acid vapors may form explosive mixtures with air. Dilute acetic acid and dilute hydrogen can undergo an exothermic reaction if heated; forming peracetic acid which is explosive at 110 degrees C. Reaction between chlorine trifluoride and acetic acid is very violent, sometimes explosive.
