Product Description

Product Description

Disodium EDTA, that is, disodium ethylenediaminetetraacetate, is an important chemical substance widely used in many fields. The following is a detailed introduction about it:

Basic Information

 

• Chemical formula: C10H14N2Na2O8
• English name: Ethylenediaminetetraacetic acid disodium salt, abbreviated as EDTA-2Na
• Molecular weight: 336.206

Physical and Chemical Properties

 

• Appearance: White crystalline powder.
• Solubility: It is easily soluble in water and slightly soluble in organic solvents such as ethanol. It has a relatively high solubility in water and can form a stable aqueous solution.
• Stability: It has good chemical stability and is not easy to decompose under general conditions. However, in a strongly acidic or strongly alkaline environment, chemical reactions may occur, affecting its performance.

Main Uses

 

• Water Treatment: It is a commonly used water softener. It can form stable complexes with metal ions such as calcium and magnesium in water, thus removing the hardness ions in water, preventing the formation of scale, improving the quality of water, and is widely used in industrial water treatment, boiler water treatment and other fields.
• Food Industry: As a food additive, it mainly plays a chelating role. It can combine with metal ions in food, such as iron and copper, to prevent these metal ions from catalyzing reactions such as the oxidation of oils and the discoloration of pigments in food, thereby extending the shelf life of food and maintaining the color and flavor of food. It is commonly found in foods such as beverages, canned goods, and sauces.
• Medical Field: It has a variety of uses in the medical field. It can be used as an antidote for heavy metals. It combines with heavy metal ions such as lead and mercury in the body to form water-soluble complexes, which are excreted from the body through urine, thus achieving the purpose of detoxification. In addition, it can also be used as a pharmaceutical excipient to regulate the stability and solubility of drugs.
• Cosmetics Industry: Added to cosmetics, it can chelate metal ions in water to prevent metal ions from having an adverse impact on the active ingredients in cosmetics, such as preventing the oxidation of oils and the discoloration of products, and improving the stability and shelf life of cosmetics.
• Chemical Analysis: It is an important complexometric titrant. In chemical analysis, it is often used to determine the content of metal ions. By forming specific complexes with metal ions, the concentration of metal ions can be determined according to the stoichiometric relationship of the reaction.

Precautions

 

• Disodium EDTA is generally safe within the normal range of use. However, if it is ingested in excessive amounts, it may cause certain harm to the human body. It may combine with some essential metal ions in the human body, such as calcium and zinc, and affect the normal physiological functions of these ions.
• When using disodium EDTA, relevant safety operation procedures and use standards should be followed, and direct contact with the skin, eyes, etc. should be avoided. In industrial production and laboratory use, protective measures should be taken, such as wearing gloves and goggles.
