Calcium acetate anhydrous what is the main use

Calcium acetate is widely used in anhydrous fields. In the field of industry, it can be used as a source of acetic acid. With its acetate root, it can produce acetic acid through chemical changes, and is needed in the pharmaceutical, dyeing and weaving industries.

In the food industry, it also has its use. It can be a preservative, which can protect food from damage and prolong its preservation. Cover it to inhibit the growth of microorganisms, so that food can last for a long time without deterioration.

In water treatment, it can remove phosphorus from water. Phosphorus is the cause of eutrophication of water bodies. Calcium acetate, anhydrous, combines with phosphate to form an insoluble substance, which sinks in the bottom of the water, reducing the amount of phosphorus in the water and purifying the water quality. < Br >
It is also found in building materials. It can be used as an additive for concrete to increase its strength and durability. It acts chemically in concrete to make the structure denser and resist external forces and natural erosion.

It is also in the field of chemical analysis and can be used as an analytical reagent. It helps chemists measure the composition and content of substances, and obtain accurate numbers based on their reactions with other substances to clarify the properties of substances.

What are the physical properties of Calcium acetate anhydrous

The acetate of calcium is also anhydrous. Its physical properties are as follows.

It is white and powder-like, fine and uniform in quality, and pure in appearance. Under room temperature, it is stable and does not melt, and can be left for a long time without changing its properties.

In terms of its density, it is about [X] grams per cubic centimeter, moderate in weight, not frivolous and difficult to aggregate, nor heavy and inconvenient to handle.

Its melting degree is quite high, and it needs to be melted at high temperature, about [X] degrees Celsius. If it is calcined with fire, it can reach this temperature and turn into a fluid.

As for solubility, it is soluble in water, and when it dissolves, it does not look very violent, slowly dissolves, and makes the water into its solution. The solution is clear and transparent, and there is no residue retention.

Furthermore, this anhydrous calcium acetate is odorless, tasteless, non-pungent, and does not disturb people's breath. It has no odor at the time of operation. Its texture is dry, non-stick and non-greasy, easy to use, can be sprinkled and thrown, and is convenient for all kinds of processes.

This is the physical properties of anhydrous calcium acetate. It is useful in industry, medicine, and various techniques. Because of its stability and good quality, it is valued by the world.

Calcium acetate anhydrous chemical properties

Calcium acetate, which is anhydrous, its chemical properties are particularly important. This salt has good solubility and can gradually dissolve in water, just like ice crystals entering a warm spring and slowly melting. Its aqueous solution is often alkaline, because acetate ions are hydrolyzed in water. It is like a weak willow fufeng and has its own state.

As for its stability, it is quite stable at room temperature. When it encounters a hot topic, it is like a soldier in danger, or changes. When heated, it may cause decomposition and produce other substances, which cannot be ignored.

In addition, it is like a smart soldier in a chemical reaction, and can interact with many substances. When encountering strong acid, it is like a battle between warriors. Acetate ions combine with hydrogen ions of strong acid to produce acetic acid. This acetic acid is volatile and has a slight smell, which can be smelled by people.

And looking at its reaction with metal ions, it may be able to form new compounds, just like a skilled craftsman combines materials to create new things. This anhydrous calcium acetate is widely used in the field of chemistry, and it is used in industry and scientific research. It is actually an important part of chemical substances.

Calcium acetate anhydrous production method

Calcium acetate anhydrous, the preparation method is mostly acetic acid and calcium carbonate in the past. First take pure acetic acid, put it in an appropriate kettle, slowly add calcium carbonate powder, during which there are bubbles escaping, which is carbon dioxide gas. When reacting, the temperature and rate should be controlled so that the two can be fully combined. The reaction formula is: $2CH_ {3} COOH + CaCO_ {3}\ longrightarrow (CH_ {3} COO) _ {2} Ca + H_ {2} O + CO_ {2}\ uparrow $. When the bubbles no longer escape, it can be seen that the calcium carbonate has been done. However, the resulting liquid still contains impurities and excess acetic acid. Then the liquid is heated and evaporated to remove its water, and when it reaches an appropriate concentration, it is cooled and crystallized. The resulting crystals, or containing crystal water, are heated and dried, and the temperature is controlled at a suitable environment to de-crystallize the water, and finally obtain calcium acetate anhydrous.

There are also those who use acetic acid and calcium hydroxide. Take an appropriate amount of acetic acid, add calcium hydroxide slowly under stirring, and control its temperature to prevent it from overheating. The reaction is: $2CH_ {3} COOH + Ca (OH) _ {2}\ longrightarrow (CH_ {3} COO) _ {2} Ca + 2H_ {2} O $. After the reaction is completed, the subsequent evaporation, crystallization and drying methods are similar to the previous methods, and anhydrous calcium acetate can also be obtained. These two methods are both common methods for preparing anhydrous calcium acetate.

Calcium acetate anhydrous in storage and transportation

Calcium acetate is anhydrous, when storing and transporting, pay attention to many matters.

First of all, moisture-proof is essential. This anhydrous agent is very easy to absorb moisture. If it encounters water vapor, it is easy to deliquescent, causing its properties to change and affecting quality. Therefore, when stored in a dry place, and the container used must be well sealed to prevent moisture from invading.

Second, the temperature must also be concerned. Overheating or too cold environment may damage its chemical stability. It should be stored in a cool and constant temperature place, protected from direct sunlight, to avoid decomposition or other chemical reactions caused by high temperature.

Furthermore, when transporting, it should be handled lightly. Although this compound is not extremely brittle, it can be handled rudely, or the packaging can be damaged, which not only affects the product, but also may be dangerous due to leakage. The packaging must be sturdy and durable, and can withstand a certain amount of external impact.

In addition, it should not be mixed with strong oxidants and other substances. Calcium acetate anhydrous meets strong oxidants, or causes violent chemical reactions, causing safety accidents. Therefore, during storage and transportation, strict classification should be carried out to ensure that there are no such dangerous substances around it.

In short, when storing and transporting calcium acetate anhydrous, moisture prevention, temperature control, light transportation and classification should not be ignored, so as to ensure its quality and safety.
