| Specification: |
?Formic acid (CAS NO.64-18-6) is a flammable colorless fuming liquid with a strong irritating smell, it is soluble in water, ethanol and ether, slightly soluble in benzene. Burning will produce nitrogen oxides emitted toxic fumes. Besides should be stored and transported in low-temperature, drying environment. Separately with bases, oxidizing agents, H hair pore-forming agent, cyanide, sand, water mist, carbon dioxide would be used if emergency. |
