Formic acid, an important chemical raw material, was first discovered by Fisher in 1670. In 1749, A.S. Marggret first prepared pure formic acid. It was named "formic acid" (from the Latin *formica*, meaning ant) because it was initially discovered through distillation of red ants.

 

Formic acid widely exists in nature, such as in the secretions of red ants, bees, caterpillars, as well as in the leaves, roots, and fruits of plants. As the simplest carboxylic acid, it has a unique structure and stronger acidity compared to other fatty carboxylic acids.

 

It is a colorless, transparent, fuming liquid with a pungent odor, with the molecular formula HCOOH, relative molecular mass 46.03, relative density 1.2196, melting point 8.4°C, freezing point 7°C, boiling point 100.7°C (50°C at 15.999×10³ Pa), refractive index 1.3714, flash point 68.9°C, viscosity 1.784 mPa·s, and ignition point 410°C. It is miscible with water, ethanol, diethyl ether, etc., and forms a high-boiling binary azeotrope with water (containing 77.5% formic acid, azeotropic point 107.3°C), which is higher than the boiling points of pure water and pure formic acid.

 

Due to the direct bonding of its carbonyl group to hydrogen, formic acid exhibits both acidic properties and certain aldehyde-like characteristics. It can form salts and esters, react with amines to produce amides, and undergo addition reactions with unsaturated hydrocarbons to form esters. Its reducing properties reflect aldehyde-like behavior-for example, it can reduce silver nitrate ammonia solution (Tollens' reagent) to metallic silver, decolorize potassium permanganate, reduce sulfur dioxide to thiosulfate ions (SO₂→S₂O₃²^-), and reduce mercury nitrate to mercury. When reacted with concentrated sulfuric acid, formic acid dehydrates to produce carbon monoxide. Heating to 160°C causes decarboxylation to generate carbon dioxide and hydrogen; catalytic decomposition (e.g., with copper-chromium, platinum, or palladium catalysts) also produces carbon dioxide and hydrogen.

 

Formic acid is highly irritating and corrosive. Inhalation of its vapor can irritate the respiratory tract and cause inflammation; skin contact can lead to blistering. Chronic poisoning may cause hematuria. The oral LD50 for rats is 1210 mg/kg, and the maximum allowable concentration in workplaces is 5×10^-6.

 

**Storage and Handling:**

- Keep away from ignition sources and heat.

- Store separately from oxidizers, alkalis, strong acids, H-blowing agents, and cyanides.

- Handle with care; avoid inversion. Prevent water absorption and packaging damage.

- For spills, flush with water (wear protective gear). In case of skin contact, immediately rinse with large amounts of water and apply ointment if necessary. For inhalation poisoning, seek immediate medical attention.

Product Application

Used for removing acidic gases from natural gas and petroleum gas, manufacturing non-ionic detergents, emulsifiers, etc;

Used as a gas chromatography stationary phase and solvent;

Ethanolamine is an intermediate used in the preparation of the carbamate insecticide hydrogen peroxide, and is also widely used as a purification solution for extracting acidic components from various gases, such as natural gas. Alkyl alcohol amide formed by ethanolamine and fatty acid is an effective foam synergist. Ethanolamine is also an intermediate of emulsifiers, used in the textile industry as an anti-static agent, anti moth agent, and cleaning agent. Hexahydrate piperazine can be prepared by cyclization and neutralization of ethanolamine hydrochloride, and piperazine can be used as a anthelmintic in the form of its phosphate or citrate salt.;

GB 2760-96 specifies that processing aids are allowed for use in the food industry.;

Monoethanolamine is mainly used as a plasticizer, vulcanizing agent, accelerator, and foaming agent for synthetic resins and rubber, as well as an intermediate for pesticides, pharmaceuticals, and dyes. It is also a raw material for synthetic detergents, emulsifiers in cosmetics, and other products. The textile industry uses it as a whitening agent, anti-static agent, anti moth agent, and cleaning agent for printing and dyeing. It can also be used as a carbon dioxide absorber, ink additive, and petroleum additive. Monoethanolamine is widely used as a purification solution for extracting acidic components from various gases, such as natural gas. Hexahydrate piperazine can be prepared by cyclization and neutralization of monoethanolamine hydrochloride. β - aminoethyl thiosulfate can be prepared by chlorination of monoethanolamine hydrochloride with sulfonyl chloride and substitution with sodium thiosulfate. This is a dye intermediate used in the production of condensed turquoise 13G. The reaction of monoethanolamine with carbon disulfide can produce the intermediate thiothiazoline, which has applications in the rubber and pharmaceutical industries.

Solvent. Organic synthesis involves removing carbon dioxide and hydrogen sulfide from gases. Gas chromatography stationary phase (maximum operating temperature 50 ºC, solvent ether), used for separating low-carbon alcohols, pyridine and its derivatives.
