Citric acid monohydrate, also known as citric acid monohydrate, is an organic compound with the chemical formula C₆HOO₇·HOO and a relative molecular weight of 210.14.Citric acid monohydrate has a mild sour taste and is odorless. The substance is colorless, transparent crystal or white granular, crystalline powder. Common forms include crystallized and powdered.It is soluble in water and ethanol, slightly soluble in ether, and the aqueous solution is weakly acidic.It is stable in the air, loses crystalline water when heated to 70-80℃, becomes anhydrous citric acid, sublimates at 100℃, and needs to be sealed and stored in a cool and dry place.In industrial production, it is used in the manufacture of beverages, food additives, detergents, cosmetics, as sour agents, chelating agents, preservatives, and antioxidants, and is also used in medicine, electroplating, water treatment, printing and dyeing and other processes.Its mild acidity can adjust flavor, freshness and color in the food field. It can be used for metal cleaning and scale removal in the industrial field. At the same time, it can be used as an acidity regulator in chemical experiments. It is widely used.

Parameter

Application Description

1. It is used as a core sour agent, preservative and antioxidant in the food industry. It is used in the processing of beverages, fruit juices, jams, candies, dairy products, canned food and other products. It can regulate food acidity, improve flavor, inhibit microbial reproduction, prevent food oxidation and deterioration, and extend shelf life.
2. The pharmaceutical industry is used in the production of pharmaceutical preparations, used as acidity regulators, flavoring agents, used to relieve symptoms such as dyspepsia and gastric acid deficiency, and can be used as an intermediate in drug synthesis for the preparation of antibiotics, vitamins and other drugs.
3. It is used as a chelating agent and cleaning agent in the chemical industry. It is used for metal surface treatment and scale removal. It can dissolve calcium carbonate and magnesium scale on the inner wall of the equipment. At the same time, it is used in the electroplating process to adjust the acidity of the plating solution and improve the quality of the coating.
4. It is used as a water quality regulator and chelating agent in the field of water treatment. It can remove heavy metal ions (such as calcium, magnesium, iron, etc.) from the water and soften the water quality. At the same time, it is used for pH regulation in wastewater treatment to reduce the content of pollutants in the water and improve water quality.
5. The cosmetics industry is used in the production of skin care products, shampoos, shower gels and other products. It is used as an acidity regulator and moisturizer. It can adjust the pH value of cosmetics and fit the pH environment of human skin. At the same time, it enhances the stability and moisturizing effect of the product.
6. It is used as a dyeing aid and color fixing agent in the textile printing and dyeing industry. It is used in the dyeing process of cotton, linen, chemical fiber and other textiles. It can adjust the acidity of the dye solution, promote uniform coloring of dyes, and improve dyeing fastness. At the same time, it is used for post-bleaching neutralization treatment of textiles.
7. It is used in the production of papermaking and detergent in the light industry, and as a gluing agent in the paper industry, which can improve the strength and water resistance of the paper; it is used as a lotion in the detergent industry to enhance the decontamination capacity of the detergent and reduce scale residues.
8. It is used as a chemical reagent in the laboratory, as an acidity regulator and chelating agent, for experimental operations such as chemical analysis and organic synthesis, and can also be used to calibrate pH meters and prepare standard buffer solutions.
