Products Description

Anhydrous citric acid is a natural component and an intermediate product of physiological metabolism in plants and animals, and is also one of the most widely used organic acids in food, medicine, chemical industry and other fields. It is colorless transparent or translucent crystal, or granular, granular powder, odorless, although a strong sour taste, but pleasant, slightly astringent. Gradually weathering in warm air, slightly deliquescent in moist air.

Citric acid

CAS: 77-92-9

Molecular formula  C6H8O7

Molecular weight 192.12

Application

Application in the food industry: anhydrous citric acid is known as the first edible acid taste agent, and China's GB2760-1996 regulations are allowed to use food acidity regulator. In the food industry, it is widely used as sour agent, solubilizer, buffer, antioxidant, deodorant, chelating agent, etc., its specific uses are too numerous to list.

Application in the pharmaceutical industry: Effervescent is a popular oral drug ingredient release system, citric acid and sodium carbonate or sodium bicarbonate aqueous solution to react together to produce a large amount of CO2(that is, effervescent) and sodium citrate, which can make the active ingredients in the drug quickly dissolve and enhance the taste ability. For example, to make laxatives and painkillers solubilizing. Citric acid syrup is a refreshing drink for patients with fever, which has the effect of correcting taste, cooling and detoxification. Citric acid is widely used in various nutritional oral liquids, buffering pH3.5 ~ 4.5, maintaining the stability of active ingredients, and strengthening the effect of preservatives. The combination of citric acid and fruit essence gives people the favorite aromatic acid taste to cover up the bitter taste of the drug, especially in the traditional Chinese medicine preparation, adding 0.02% citric acid to the liquid ingredient can form a complex of trace iron and copper, delaying the degradation of the active ingredient. The use of 0.1% ~ 0.2% citric acid in chewing tablets can improve the flavor of tablets and make them have lemon flavor.

Application in industry:

1. Metal purification The citric acid based metal purification formula can effectively remove oxides formed on the surface of ferrous and non-ferrous metals. As a weak organic acid, it can cause slight damage to the metal surface layer, while as a metal ion chelating agent it accelerates the migration of metal oxides. In order to eliminate metal oxide stress cracks and minimize the corrosion brittleness of high-strength steel, citric acid is used to remove rust instead of inorganic strong acids. In boilers, heaters, superheater tubes, dirty reactors, and stainless steel equipment, citric acid prewashing and purification are generally used to remove iron and copper oxides, especially where chlorides are not allowed. The purification reaction of citric acid solution should be carried out when it is higher than 37.8℃, and the purification time should be extended correspondingly when it is lower than 37.8℃. The amount of citric acid and the action conditions should be adjusted by increasing or decreasing the estimated precipitation amount. Citric acid is a highly efficient chelating cleaning agent, which is effective for dirt such as calcium, magnesium, iron, chromium and copper, and is widely used for cleaning various metal surfaces. After washing, the wastewater is biodegradable and does not pollute the environment. In recent years, citric acid is suitable for the chemical treatment of metal purification, but also for the non-polluting ashing of waste solvents, citric acid molecules in the ash into CO2 and water vapor and valuable metals can be recovered from the ash, for toxic or radioactive elements can be fully closed for chemical treatment.

2. Detergent sodium citrate can increase decontaminating performance, in many household detergent products can accelerate biodegradation, can be used as a phosphate substitute, a large number of used in laundry detergent, detergent, sodium citrate and aluminum silicate together to enhance the cleaning agent cleaning effect is very effective. Industrial grade 50% citric acid solution is used as raw material in these products. In non-synthetic detergent solutions, citric acid is also used in hot water extraction as a carpet cleaner, bath and textile softener due to its buffering effect and the ability to chelate trace metals.

3. Soilless cultivation agriculture in foreign countries using trace element plant nutrient solution soilless cultivation has long been common, and has begun to develop in China. In order to remove some excessive elements such as copper, zinc, manganese and chromium from the soil, citric acid is generally used to chelate such elements. The use of citric acid instead of phosphate can achieve a satisfactory yield increase.

4. The application of citric acid in minerals and pigments has a dispersing effect, which can reduce the viscosity of some important slurry raw materials. In mining, for example, the viscosity of phosphate rock powder in hydraulic transportation often becomes the main reason of clay expansion. The expansion can be controlled by citric acid treatment, which makes the slurry raw material easy to transport. Citric acid also reduces the precipitation of the concentrated raw material of titanium dioxide, making it easy to handle and transport in whole form. Citric acid can also be used as a dispersant for low-pulp adhesives, paint and textile raw materials, and titanium dioxide.
