Formic Acid Uses One of the most general industrial uses of formic acid is in the manufacture of leather. Because it is so acidic, formic acid has verified itself to be wonderful for use in this method. When used properly, formats can deeply increase the absorbing capability of otherwise smooth surfaces as well as support to the deduction of these surfaces with the equipment and extra technologies. Agriculture accounts for the extremely high percentage of formic acid make use of worldwide. Because of its natural antibacterial properties formic acid has been achieved very high use as both a clean preservative and pesticide. In addition to providing a positive level of clean support formic acid really allows grass to start fermentation at a lower temperature, deeply reducing the generally time that it takes to manufacture as increasing the nutritional importance of the complete product.
Formic Acid Uses – Nature
A colorless transparent fuming liquid with a strong pungent odor. It is a strong acid. It is miscible with water in any ratio and forms an azeotropic mixture above the boiling point of both. Miscible with many organic solvents, but insoluble in hydrocarbons. Flammable, in the long-term storage of 30 degrees Celsius, formic acid will occur slow decomposition, release of carbon monoxide. Its vapor and air to form an explosive mixture, fire, high heat caused by combustion explosion. Reactions with strong oxidants may occur. It has strong corrosion. Corrosion of aluminum, cast iron, steel, certain plastics, rubber and coatings.
Formic acids – Preparation Method
The desulfurized and compressed carbon monoxide is passed into a reactor containing 20% ~ 30% sodium hydroxide solution and reacted at 160~200 ℃ and 1.4 ~ 1.6MPa to form sodium formate, then 76% formic acid-water azeotrope was obtained by treatment with dilute sulfuric acid, which can be further concentrated and refined.
Formic Acid Uses
formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the resulting formate can be dissolved in water, so it can be used as a chemical cleaning agent. Formic acid can be used for cleaning equipment containing stainless steel materials. Formic acid has good volatility and is easily removed after cleaning, so it can be used for cleaning projects sensitive to residues. In the cleaning concentration, formic acid is non-toxic and harmless to human body, and the corrosion of metal is not as strong as that of inorganic acid, so it is a safe cleaning agent.
Formic acids – Safety
mice were injected orally and intravenously with LD50:1100 mg/kg, 145mg/kg. Inhalation of formic acid vapor can severely irritate the mucous membranes of the nose and mouth and cause inflammation. With strong corrosive, irritating, can cause human body burns. The concentration of formic acid in the workplace is allowed to be 5g/m3. When dealing with Concentrated formic acid, protection must be provided, eyes and skin contact with formic acid, should be immediately washed with water. Store in a cool, dry, ventilated place. Keep away from fire and heat source. Keep the container sealed. Should be stored separately from the oxidant, alkali.
