    Formic Acid

    (64-18-6)
    Acid is one of the basic organic chemical raw materials. It is widely used in pesticides, leather, textiles, printing and dyeing, medicine and rubber industries. It can also be used to prepare various solvents, plasticizers, rubber coagulants, animal feed additives and new processes to synthesize insulin Wait. In my country~"s formic acid consumption, the pharmaceutical industry accounts for approximately 45%, the chemical industry accounts for approximately 30%, and other sectors such as light industry and textiles account for approximately 25%. Formic acid is one of my country~"s important export chemical products. At present, all formic acid production in my country adopts sodium formate method. Formic acid is often used as a substitute for cheap, less volatile and corrosive inorganic acids, and is widely used in the light industry. In the textile and printing and dyeing industries, formic acid is used as an agent for eliminating nitrous acid gas produced by the Indicotin sodium nitrite method, as a dyeing aid for weak acid dyes and neutral complex dyes, and for dyeing nylon with reactive dyes. Formic acid will not remain on the fabric during printing and dyeing. It has stronger acidity than acetic acid and can reduce hexamedium chromium. Therefore, it can improve the utilization of dye in the chromium mordant dyeing process. The use of formic acid instead of sulfuric acid can avoid the degradation of cellulose, and the acidity is moderate, and the dyeing is familiar, so it is an excellent dye aid. Formic acid, as a substitute for inorganic acids, is used for decolorization, depilation, neutralization of lime in tanning and prevention of mildew in wet leather. Using formic acid as a coagulant can raise the quality of high natural rubber, reduce production costs, and can also be used for the regeneration of waste rubber. The use of formic acid as a feed additive has great potential in silage. Formic acid has the function of inhibiting or preventing the growth of mold. It can change the natural fermentation form of feed. Fatty acid is often added to improve the anti-mold effect. Foraging cows treated with formic acid can prevent milk loss in winter, and the fattening effect has also been significantly improved. In the food industry, formic acid is used for disinfection and antisepsis in the wine industry, as a cleaning and disinfectant for cans, as a preservative for fruit juices and food. A large number of derivatives of formic acid are intermediates of medicines, pesticides, dyes, fragrances, solvents, used in the manufacture of borneol, aminopyrine, caffeine, vitamin B1, analgin, trimethoprim, triflurazine, tricyclazole, dimethyl Base formamide, etc. Among formic acid derivatives, substituted formamides and formates are widely used in industry (for formamide derivatives, see the item). The esters of formic acid are widely used in the perfume industry, such as: ethyl formate-fruit flavors such as peach and raspberry; isoamyl formate-fruit flavor, leather flavor; hexyl formate-apple flavor; heptyl formate ——Apricot, plum, peach and other fruit essences; n-decyl formate—for orange blossom essence and iris oil; benzyl formate—for frangipani and other floral and soap essences; cinnamyl formate—for frangipani and moonshine etc. Use; citronellyl formate-for rose, osmanthus, wild lily and other flavors; syringyl formate-for carnation flavor, etc.; geranyl formate-rose, orange blossom, gerbera and other flavors; formic acid Camphor esters-lavender, bergamot and other flavors; menthyl formate-cosmetic flavors, spray flavors; phenethyl formate-white rose, orchid, chrysanthemum and other flavors; thyme formate-cosmetic fragrances. Used as analytical reagent, such as reducing agent, to prepare buffer solution. It is also used in the preparation of pure carbon monoxide and pesticides. Sterilization and mildew prevention in pulp manufacturing. It can also manufacture leather softeners, rubber coagulants, mordants for printing and dyeing, dyeing and treating agents for fibers and paper, plasticizers and animal feed additives. It can also be used as a preservative in cosmetics. The maximum allowable content in cosmetics is 5% (acid). Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the formate generated can be dissolved in water, so it can be used as a chemical cleaning agent. Formic acid does not contain chloride ions and can be used to clean equipment containing stainless steel. Used in the manufacture of chemicals, rubber coagulants, textiles, printing and dyeing, electroplating, etc.
