الوصف

Property:
Colorless transparent oily liquid smoke,with the irritating odor.
Formic acid is miscible with water and most polar organic solvents, and somewhat soluble in hydrocarbons. In hydrocarbons and in the vapor phase it consists of hydrogen-bonded dimers rather than individual molecules. Owing to its tendency to hydrogen-bond, gaseous formic acid does not obey the ideal gas law. Solid formic acid (two polymorphs) consists of an effectively endless network of hydrogen-bonded formic acid molecules. This relatively complicated compound also forms a low-boiling azeotrope with water (*2.4%) and liquid formic acid also tends to supercool.

Uses
The principal use of formic acid is as a preservative and antibacterial agent in livestock feed. When sprayed on fresh hay or other silage, it arrests certain decay processes and causes the feed to retain its nutritive value longer, and so it is widely used to preserve winter feed for cattle. In the poultry industry, it is sometimes added to feed to kill salmonella bacteria.

Reagent in organic chemistry
Formic acid is a source for a formyl group for example in the formylation of methylaniline to N-methylformanilide in toluene. In synthetic organic chemistry, formic acid is often used as a source of hydride ion. The Eschweiler-Clarke reaction and the Leuckart-Wallach reaction are examples of this application. It or more commonly its azeotrope with triethylamine, is also used as a source of hydrogen in transfer hydrogenation.

Other uses
l It is used to process organic latex (sap) into raw rubber.
l Beekeepers use formic acid as a miticide against the Tracheal (Acarapis woodi) mite and the Varroa mite.
It is of minor importance in the textile industry and for the tanning of leather.
Some formate esters are artificial flavorings or perfumes.
It is the active ingredient in some brands of household limescale remover.
It is used in laboratories as a solvent modifier for HPLC and CE separations of proteins and peptides, especially when the sample is being prepared for mass spectrometry analysis.
Fuel cells that use modified formic acid have been reported.
