Chemical properties and stability of formic acid, followed by Zibo Rainbow Chemical Co. Ltd. the small one to know about it!
Formic acid can be used in many walks of life, its use is widespread, the company below small make up for you:
Formic acid, also called formic acid, molecular formula is HCOOH. Formic acid colorless pungent odor, and corrosion, foaming swelling after exposure of human skin. Properties of formaldehyde with acid and aldehyde. In the chemical industry, formic acid is used in rubber, pharmaceuticals, dyes, leather type industry.
1 chemical properties: formic acid as reducing agent and strong, silver mirror reaction can occur. In saturated fatty acids in the most acidic dissociation constant is 2.1 × 10-4. In the room temperature gradually decompose into carbon monoxide and water. With concentrated sulfuric acid and heating to 60~80 DEG C, decompose and release carbon monoxide. Formic acid is heated to 160 ℃ which emits carbon dioxide and hydrogen. Alkali metal salt are heated to 400 ℃ oxalate acid.
2 formic acid to dissolve fat. Formic acid vapor inhalation of irritant severe nasal and oral mucosa, and can cause inflammation of. In the treatment of concentrated acid, must wear protective masks and rubber gloves. The workshop must have a shower and eye wash equipment, work place should have good ventilation environment, the maximum allowable concentration of formic acid in the air of area 5*10-6. Inhalation poisoning to leave the scene immediately, breathe the fresh air, and inhalation of aerosolized sodium bicarbonate 2%. Once infected with formic acid, rinse immediately with plenty of water, do not use wet cloth to wipe.
