개요Formic acid is a clear, colorless liquid with a pungent odor. Formic acid was first isolated from certain ants and was named after the Latin formica, meaning ant. It is made by the action of sulfuric acid on sodium formate, which is produced from carbon monoxide and sodium hydroxide. It is also produced as a by-product in the manufacture of other chemicals such as acetic acid. It can be anticipated that use of formic acid will continuously increase as it replaces inorganic acids and has a potential role in new energy technology. Formic acid toxicity is of a special interest as the acid is the toxic metabolite of methanol.

출처Widespread in a large variety of plants; reported identifed in Cistus labdanum and the oil of Artemisia trans- iliensis; also found among the constituents of petit grain lemon and bitter orange essential oil; reported found in strawberry aroma Reported found in apple, sweet cherry, papaya, pear, raspberry, strawberry, peas, cheeses, breads, yogurt, milk, cream, buttermilk, raw fsh, cognac, rum, whiskey, cider, white wine, tea, coffee and roasted chicory root

역사Formic acid is taken from the Latin word forant, formica. Naturalists had observed the acrid vapor from ant hills for hundreds of years. One of the earliest descriptions of formic acid was reported in an extract of a letter written from John Wray (1627–1705) to the publisher of Philosophical Transactions published in 1670. Wray’s letter reported on “uncommon Observations and Experiments made with an Acid Juyce to be Found in Ants” and noted the acid was previously obtained by Samuel Fisher from the dry distillation of wood ants. Formic acid is found in stinging insects, plants, unripe fruit, foods, and muscle tissue. Jns Jacob Berzelius (1779–1848) characterized formic acid in the early 19th century, and it wasfirst synthesized from hydrocyanic acid by Joseph Louis Gay-Lussac (1778–1850) at about the same time. A number of synthetic preparations of formic acid were found in the first half of the 19th century. Marcellin Berthelot (1827–1907) discovered a popular synthesis using oxalic acid and glycerin in 1856; he and several other chemists from his period found syntheses of formic acid by heating carbon monoxide in alkaline solutions.

일반 설명Formic acid is the simplest carboxylic acid. Crystal structure study by single-crystal X-ray diffraction technique at -50°C has shown that it has an orthorhombic structure with space group Pna. The photodegradation of formic acid has been investigated using ab intio calculations and time-resolved Fourier transform infrared spectroscopy. Its utility as a fuel in direct fuel cells has been studied. The momentum distribution for its monomer have been evaluated by electron momentum spectroscopy (EMS).
