Formic Acid, is also called Methanoic Acid.
Formic Acid is contained in the ant and bees secretions, people made
distillation ants and obtained Formic Acid, reason has this name. Formic Acid
is colorless and stimulating odor and corrosive, foaming swelling after
exposure of human skin. The melting point of it is 8.4 ℃, and the boiling point of it is
100.8 ℃. Due to the
special structure of Formic Acid, one of its atoms of hydrogen and carboxyl
group is directly connected. It can also be seen as a hydroxyl formaldehyde.
Therefore, Formic Acid is with acid and aldehyde properties at the same time.
In the chemical industry, Formic Acid is used in rubber, pharmaceuticals, dyes,
leather type industry.
The properties of Formic Acid:
Formic Acid and water and in the majority
of polar organic solvents miscible, also have certain solubility in
hydrocarbons. In hydrocarbon and gaseous, Formic Acid is by the dimers form of
hydrogen bonding. In the gaseous, hydrogen bonding leads to large deviation
between the acid gas and ideal gas equation of state. Liquid and solid acid is
by continuous Formic Acid molecules by hydrogen bonding. Formic Acid has the
same nature with most other carboxylic acids, although typically do not
generate chloride or acid anhydride. Until recently, all attempts to Formic
Acid into the derivatives of attempt to product carbon monoxide. Phthalic
anhydride can be obtained by formyl fluoride and Sodium Formate at minus 78 ℃. Benzoyl chloride can be made of
hydrogen chloride gas through minus 60 ℃ 1-formyl imidazole. Dehydration of Formic Acid decomposition to
carbon monoxide and water. Formic Acid is of a similar reducibility and
aldehyde.
Solubility of Formic Acid:
Miscible with water, not soluble in
hydrocarbons, miscible with alcohol. HCOOH also known as Formic Acid, is a
colorless, flammable smoke, pungent odor of the liquid, has a strong corrosive,
Formic Acid and water, ethanol, ethyl ether, glycerol and other miscible
volatile liquids with strong corrosion and spicy spicy sour.
