What are the Common Uses of Aluminum Acetate?

Aluminum (Aluminum) and acetic acid (Acetate) are compounds with many common uses.

First, in the field of medicine, it is often used as an astringent agent. This is because aluminum ions can bind to proteins, promote protein coagulation, and then play a astringent effect. In the treatment of some skin diseases, such as mild burns, abrasions, eczema, etc., preparations containing aluminum acetate can help reduce local exudation, redness and swelling, and achieve the purpose of relieving pain.

Second, in water treatment, it can act as a water purifier. The suspended particles in water are mostly negatively charged, while the aluminum ions produced by the dissolution of aluminum acetate are positively charged. The two attract each other, causing the suspended particles to condense and become larger, and eventually settle. This can effectively remove impurities in water and improve water quality.

Third, in the textile printing and dyeing industry, aluminum acetate is also used. It can be used as a mordant to enhance the bonding force between dyes and fabrics. After the fabric is treated with aluminum acetate, the surface absorbs aluminum ions, which can react with dye molecules, so that the dye can adhere more firmly to the fabric, improve the dyeing effect, and make the color more vivid and lasting.

Fourth, in the paper industry, it can be used for sizing. It can improve the water resistance of paper, so that when the paper is in contact with moisture, it is not easy to deform due to water absorption and reduce strength. This is due to the interaction between aluminum acetate and paper fibers, forming a protective film on the surface of the fibers to block moisture intrusion.

How to Use Aluminum Acetate

Aluminum acetate, that is, aluminum acetate, is used as follows:

Aluminum acetate is often used externally in the form of a solution. For skin diseases, it can be used as a wet compress. If there is skin redness, exudation, etc., take an appropriate amount of aluminum acetate solution to wet the gauze, and then apply it lightly to the affected area, which can help reduce local swelling, converge exudation, and achieve soothing effect.

And in some inflammatory skin diseases, such as acute eczema in the exudation stage, wet compress of aluminum acetate solution can make the local environment dry, block external stimuli, and help relieve the disease. And if there is a mild skin infection, aluminum acetate solution also has a certain bacteriostatic effect and assists in controlling infection.

When using, pay attention to the concentration of the solution. Usually follow the doctor's instructions to prepare the appropriate concentration to prevent excessive concentration from irritating the skin and causing skin discomfort, such as burning pain, redness, etc. At the same time, the frequency and duration of application should also follow the doctor's advice. Normally several times a day, each application time should be moderate, and should not be too long. If there is an abnormality in the skin during application, such as an allergic reaction, stop using it immediately and seek medical treatment.

Side Effects of Aluminum Acetate

The reaction between aluminum and acetic acid (Acetate) produces substances that have considerable side effects on the human body and the environment.

For the human body, if you accidentally ingest aluminum-containing acetate, you may have adverse effects. Although aluminum is not an essential element of the human body, excessive intake will accumulate in the body. Aluminum ions may interfere with the normal operation of the nervous system, and in the long run, it may increase the risk of neurodegenerative diseases, such as Alzheimer's disease. Because aluminum can affect the transmission of neurotransmitters and destroy the normal function of nerve cells. In addition, aluminum is also harmful to bone health. It can interfere with the balance of calcium and phosphorus metabolism, weaken bone density, and make the human body susceptible to bone diseases such as osteoporosis.

Looking at its impact on the environment, when aluminum-containing acetate enters the water body, it will change the chemical properties of the water body. Aluminum ions will affect the survival of aquatic organisms. High concentrations of aluminum can cause damage to the gills of fish, interfere with their respiration and ion regulation, and reduce the survival rate and reproductive ability of fish. For aquatic plants, aluminum can inhibit their root growth and nutrient absorption, affect photosynthesis, and destroy the balance of aquatic ecosystems.

In the soil environment, if a large amount of aluminum-containing acetate accumulates, it will change the soil pH and structure. Aluminum ions will replace other cations in the soil, affecting soil fertility and microbial activity. Soil microorganisms participate in the decomposition of organic matter and nutrient cycling, and the inhibition of their activity will affect soil ecological functions and is not conducive to plant growth. Therefore, when using aluminum and acetic acid-related reaction products, it is necessary to carefully consider their potential side effects to protect human health and the ecological environment.

How to Store Aluminum Acetates

For those who have aluminum acetic acid, their nature is special and they need to be well hidden. The key to its storage method is to avoid moisture. Cover the tide can change the quality of the medicine. If it is exposed to wet places and the water vapor gradually soaks, it will definitely change its chemical properties and reduce its medicinal power. Therefore, when choosing dry storage, such as placing it in pottery urns or glass bottles, strictly seal its mouth, and do not let moisture into it.

Next time, it needs to be protected from light. Light can also disturb its properties and cause chemical changes. It is better to hide in a dark room, or use a black-colored utensil to hold it, so that the light cannot penetrate, which can ensure its stability.

Also, temperature is also necessary. Do not use a place with high temperature, which can promote its decomposition and cause the drug to gradually lose its power. Do not put it in a cold place, which can condense its quality or cause its properties to change. It should be stored in a place at room temperature to keep its properties flat.

And the reservoir is also exquisite. Do not use iron tools to come into contact with it. Aluminum acetic acid and iron are easy to react, resulting in impure drug quality. Use corrosion-resistant tools, such as ceramics and glass, to ensure its quality.

If you can hide it properly, the properties of aluminum acetic acid can last for a long time, and the medicinal power can be constant, so as to prepare for medical needs. If you can't hide it, it is easy to lose its effect and delay patients. Therefore, those who hide aluminum acetic acid must adhere to this number in order to obtain it.

How Does Aluminum Acetate React with Other Substances?

Aluminum acetate (ie aluminum acetate), this substance often shows all kinds of wonderful changes in chemical reactions.

If you encounter alkalis, such as sodium hydroxide, the two meet, just like a swordsman, and immediately react. In aluminum acetate, aluminum ions and hydroxide ions quickly combine to form aluminum hydroxide precipitation, just like cloud condensation. The reaction formula is as follows: $Al (CH_ {3} COO) _ {3} + 3NaOH\ longrightarrow Al (OH) _ {3}\ downarrow + 3CH_ {3} COONa $. Aluminum hydroxide is a white flocculent precipitation, which is quite strange.

If there is a carbonate, take sodium carbonate as an example, and the aluminum acetate solution blends with it, it will change differently. The double hydrolysis reaction between aluminum ions and carbonate ions occurs in water, and the bubbles rise and precipitate in an instant. This is because the hydrolysis of aluminum ions is acidic and the hydrolysis of carbonate ions is alkaline, and the two promote each other's hydrolysis reaction. The reaction is roughly: $2Al (CH_ {3} COO) _ {3} + 3Na_ {2} CO_ {3} + 3H_ {2} O\ rightarrow 2Al (OH) _ {3}\ downarrow + 6CH_ {3} COONa + 3CO_ {2}\ uparrow $, the bubbles are carbon dioxide, and the precipitation is aluminum hydroxide. < Br >
If it encounters some metal salts, such as silver nitrate solution, the acetate ion in aluminum acetate will combine with the silver ion to form a silver acetate precipitate. Due to the relatively small solubility of silver acetate, the white precipitate is slowly precipitated, and the reaction formula is: $Al (CH_ {3} COO) _ {3} + 3AgNO_ {3}\ longrightarrow 3AgCH_ {3} COO\ downarrow + Al (NO_ {3}) _ {3} $.

And aluminum acetate will also hydrolyze itself in water, making the solution slightly acidic. Although the hydrolysis process is slow, it continues, and the aluminum ions are gradually converted into the state of aluminum hydroxide colloid. This colloid has adsorption properties and can be used for water purification and other things, which is quite useful for people's livelihood.

In summary, the reaction of aluminum acetate with other substances, or the formation of precipitation, or the escape of gas, or the wonder of hydrolysis, there are many changes, which is really interesting in the chemical world.
