As a green feed additive.
Aroma enhancer. Mainly used to formulate flavors such as pineapple, rum and fumigation. Both disinfection and antiseptic effects.
Sterilization and mildew in pulp manufacturing.
Formic acid is one of the basic organic chemical raw materials, widely used in pesticides, leather, textile, printing and dyeing, medicine and rubber industries, etc. It can also be used to prepare various solvents, plasticizers, rubber coagulants, animal feed additives and new processes for synthesizing insulin. Wait. In China's formic acid consumption, the pharmaceutical industry accounts for about 45%, the chemical industry accounts for about 30%, and other departments such as light industry and textiles account for about 25%. Formic acid is one of the important export chemical products in China. At present, all of the formic acid production in China uses the sodium formate method. Formic acid is often used as a substitute for inexpensive, volatile and less corrosive inorganic acids and is widely used in the light industry. In the textile and printing and dyeing industries, formic acid is used as a nitrous acid gas-eliminating agent for the elimination of the indicine sodium nitrite method, a weak acid dye and a neutral complex dye dyeing assistant, and a dye dye for the reactive dye-dyed nylon. Formic acid does not remain on the fabric during the printing process. The acidity is stronger than that of acetic acid, which can reduce the hexa-chromium. Therefore, the dye utilization rate can be improved in the chrome mord process. The use of formic acid instead of sulfuric acid avoids the degradation of cellulose, and it has a moderate acidity and dyeing, so it is an excellent dyeing aid. Formic acid is used as a substitute for inorganic acids for decolorizing, depilating, neutralizing lime and preventing mildew of wet leather. The use of 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 to make feed additives has great potential in silage. Formic acid has the function of inhibiting or preventing the growth of mold, and the feed can change the natural fermentation form, and fatty acid is often added to enhance the anti-mildew effect. Feeding cows with formic acid treated with formic acid can prevent milk production in winter and the fattening effect is also significantly improved. In the food industry, formic acid is used in the brewing industry for disinfection, preservation, use as a cleaning and disinfecting agent for cans, and as a preservative for juices and foods. A large number of derivatives of formic acid are intermediates for pharmaceuticals, pesticides, dyes, perfumes, solvents, used in the manufacture of borneol, aminopyrine, caffeine, vitamin B1, analgin, insecticidal, triadimefon, tricyclazole, dimethyl Carboxamide and the like. The substituted formamides and formates in the formic acid derivatives are industrially used more (derivatives of formamide are listed in this product). The esters of formic acid are widely used in the perfume industry, such as: ethyl formate - peach, raspberry and other fruit flavors; isoamyl formate - fruit flavor, leather flavor; formic acid ester - apple flavor; heptyl formate - apricot, plum, peach and other fruit flavors; n-decyl benzoate - neroli and iris oil; benzyl formate - frangipani and other floral and soap flavors; cinnamate - fragrant and fragrant Used; citronellic acid for use in roses, sweet-scented osmanthus, wild lily and other flavors; syringyl formate - used in carnation flavors; geranyl formate - rose, orange blossom, fragrant leaves and other flavors; formic acid Ester ester - lavender, bergamot and other flavors; menthyl formate - cosmetic essence, spray essence; phenylethyl formate - white rose, orchid, chrysanthemum and other flavors; formic acid thyme ester - cosmetic spices.
Reducing agent for the determination of arsenic, antimony, aluminum, copper, gold, indium, iron, lead, manganese, mercury, molybdenum, silver and zinc, testing bismuth, antimony and tungsten, testing aromatic primary and secondary amines, determining molecular weight and A solvent for crystallization, a methoxy group was determined, and used as a fixing agent in microscopic analysis to produce a formate.
