Sodium acetate, trihydrate what is the main use

Sodium acetate trihydrate has a wide range of main uses. In the chemical industry, it is often used as a buffer. Because it can adjust the pH of the solution and maintain the pH of the system, it provides a suitable acid-base environment for the reaction in many chemical reactions to ensure the smooth progress of the reaction. For example, in some organic synthesis reactions that are sensitive to pH, sodium acetate trihydrate can ensure that the reaction is within a specific pH range, improving the purity and yield of the product.

In the printing and dyeing industry, it plays an important role as a mordant. In the dyeing process, it can help the dye to better adhere to the fabric fibers, making the dyeing more uniform and firm, enhancing the dyeing effect of the fabric, and reducing fading. For example, when dyeing cotton fabrics, the use of sodium acetate trihydrate can make the color more vivid and lasting. < Br >
In the food industry, it can be used as a preservative. It can inhibit the growth and reproduction of microorganisms and prolong the shelf life of food. Adding an appropriate amount of sodium acetate trihydrate to baked goods such as bread and cakes can prevent mildew and maintain good quality and taste of food.

In the field of sewage treatment, it can be used as a carbon source. It provides energy for denitrifying bacteria, helps them reduce nitrate to nitrogen, realizes denitrification treatment of sewage, improves water quality, reduces the risk of eutrophication of water bodies, and maintains the ecological environment.

In the laboratory, it is also a commonly used chemical reagent. It is used for preparing buffer solutions, conducting chemical analysis and qualitative and quantitative experiments, etc., providing convenience for scientific researchers to carry out various experiments.

Sodium acetate, trihydrate what are the physical properties

Sodium acetate trihydrate is a common chemical substance. It has the following physical properties:
The appearance is mostly colorless and transparent or white particle crystalline, which makes it easy to identify in appearance. The colorless and transparent ones are pure and transparent, and the white particle crystals also have a unique crystal form.
The melting point is about 58 ° C. At this temperature, the sodium acetate trihydrate melts from a solid state to a liquid state. This property has important applications in specific temperature control chemical reactions or material processing.
is highly soluble in water, dissolves quickly and can combine well with water molecules to form a uniform solution. Its aqueous solution is weakly alkaline, with a pH value of about 8.5-9.5. This alkaline property plays a role in some systems that need to adjust pH. < Br > The density is about 1.45 g/cm ³. Compared with common liquids and some solids, this density allows it to operate according to the density difference during the mixing or separation of substances.
In addition, the substance has strong hygroscopicity and is easy to absorb moisture in humid air. When storing, attention should be paid to moisture-proof, otherwise it is easy to affect its chemical properties and use effect due to water absorption.

Sodium acetate, trihydrate how to store

The sodium acetate trihydrate is also sodium acetate trihydrate. This material is relatively stable, but it also needs to be properly stored to ensure that its quality remains unchanged.

The way to store it, first choose a suitable place. It should be placed in a cool, dry and well-ventilated place. If it is covered in a humid place, sodium acetate trihydrate is easy to absorb moisture and deliquescence. For example, if you are in the rainy season in the south of the Yangtze River, the air humidity is quite high. If you don't pay attention, this substance will be easily invaded by moisture and gradually melt into a paste, which will damage its effectiveness.

Furthermore, the choice of container is also crucial. When using a sealed container to prevent excessive contact with the outside air. Choose corrosion-resistant utensils such as glass and plastic. If a metal container is used, or due to acetate ions, there is a risk of corrosion.

Also, avoid hot topics at high temperatures. Although sodium acetate trihydrate has a certain thermal stability, if it is overheated, it may lose its crystal water or even decompose. In case of hot summer, the sun is hanging high, if it is exposed to sunlight, the temperature rises sharply, and its properties may change.

When it exists, it should also avoid coexistence with strong oxidants, strong acids and other substances. Because sodium acetate trihydrate encounters such substances, it may cause a violent chemical reaction, causing safety risks.

In short, the storage of sodium acetate trihydrate needs to be cautious, pay attention to the environment, containers and other factors, in order to ensure its purity and effectiveness.

Sodium acetate, trihydrate in different fields of application

Sodium acetate trihydrate is useful in various fields. In the field of chemical industry, it is often used as a raw material for organic synthesis. It can be used to prepare acetic acid, acetate esters and many other organic compounds. Because it contains acetate, it can participate in a variety of chemical reactions, just like in esterification reactions, and can be a key material for providing acetic acid roots.

In the printing and dyeing industry, it also has important functions. It can be used as a buffer to stabilize the pH value of the dyeing bath. In this way, when the fabric is dyed, it can make the color more uniform and bright, and can avoid the risk of dye hydrolysis or fabric damage due to pH fluctuations.

In the food industry, sodium acetate trihydrate can be used as a preservative and acidity regulator. It can inhibit the growth of microorganisms and prolong the shelf life of food. And can adjust the acidity of food, improve the flavor of food, and make the taste better.

In the field of water treatment, it can be used as a carbon source. In the sewage biological treatment process, it can provide an electron donor for denitrifying bacteria, promote denitrification, and reduce nitrate to nitrogen, thereby effectively removing nitrogen in sewage and improving water quality.

In the pharmaceutical field, or as a pharmaceutical excipient. It can provide a specific chemical environment for pharmaceutical preparations, which is helpful for the stability and solubility of drugs, and ensures the quality and efficacy of drugs.

Sodium acetate, trihydrate chemical properties of what is

Sodium (Sodium) is an active metal that reacts violently when exposed to water, releasing hydrogen and producing sodium hydroxide. The reaction is quite rapid, or it may cause combustion or even explosion.

Sodium acetate, trihydrate, often appears colorless and transparent crystals. It has many characteristics. This salt can be dissociated in water, and acetate ions will partially hydrolyze, making the solution weakly alkaline. Because of its hydrolysis, it can buffer the pH of the solution.

Sodium acetate trihydrate has a melting point of about 58 ° C. When heated above the melting point, it will melt into a liquid state. When cooled, it is easy to crystallize, and the crystallization process will release heat. This property makes it used as a heat storage material in some hand warmers and other products. It is also soluble in water, with good solubility in water, while its solubility in organic solvents is relatively limited. In many chemical experiments and industrial production, sodium acetate trihydrate is often used as a buffer, mordant, etc. In the food industry, it can also be used as a preservative and flavoring agent, which can impart a specific flavor to food and inhibit the growth of microorganisms to extend the shelf life of food.
