General Description
Formic Acid is not only an acid but also an aldehyde; it reacts with alcohols to form esters as an acid and it is easily oxidized which imparts some of the character of an aldehyde. Pure formic acid is a colorless, toxic, corrosive and fuming liquid, freezing at 8.4 C and boiling at 100.7 C. It is soluble in water, ether, and alcohol. It irritates the mucous membranes and blisters the skin. It is prepared commercially from sodium formate with the reaction of condensed sulfuric acid. Formic acid is used as a chemical intermediate and solvent, and as a disinfectant. It is also in processing textiles and leathers, electroplating and coagulating latex rubber.
