Formic Acid

CAS#: 64-18-6

Synonyms: Hydrogen carboxylic acid; methanoic acid.

Uses: Dyeing and finishing of textile; leather treatment; chemicals ( formates, oxalic acid, organic esters); manufacture of  fumigants,, insecticides, refrigerants; solvents for perfumes, laquers; electroplating; brewing (antiseptic); silvering glass; cellulose formate; natural latex coagulant; ore flotation; vinyl resin plasticizers.

Hazard: Liquid causes skin and eye burns.  Vapors are irritating and painful to breath.  Vapor exposure may cause nausea and vomiting.  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.
