POTASSIUM FLUORIDE ON CELITE (R)

Potassium (POTASSIUM) and potassium fluoride (FLUORIDE) are loaded on diatomaceous earth (CELITE ®). When using the combination of these three, there are many things to pay attention to.

The first thing to pay attention to is its chemical activity. Potassium is an extremely active metal, which reacts violently in contact with water, generates hydrogen and emits a lot of heat, and can even cause combustion and explosion. Potassium fluoride is corrosive and can cause burns when in contact with skin and mucous membranes. Although the stability of the two is slightly increased in diatomaceous earth, it still needs to be treated with caution. During operation, avoid contact with water and moisture, and store in a dry place to prevent accidental changes.

Furthermore, it is related to its toxicity. Potassium fluoride is toxic and can be inhaled, ingested or absorbed through the skin, which can endanger health. During use, it should be done in a well-ventilated place, and protective equipment such as gas masks, protective gloves, protective clothing, etc. should be worn when necessary to prevent potassium fluoride from invading the human body and harming health.

In addition, when taking it, the weighing must be accurate. Because of its active and toxic chemical properties, the dosage is wrong, or the reaction may be out of control, or it may cause a safety accident. After taking it, it should also be properly sealed to prevent deterioration or leakage.

Handling this substance, you should also be familiar with relevant emergency treatment methods. If you accidentally come into contact with the skin, you should rinse it with plenty of water immediately; if it enters the eyes, you need to rinse it immediately and seek medical attention. In case of fire, due to the reaction of potassium with water, it is not possible to extinguish the fire with water, and suitable fire extinguishing agents such as dry sand should be used.

In short, the handling of potassium and potassium fluoride loaded on diatomite must be treated with scientific methods and prudence, and always pay attention to safety in order to avoid disasters and ensure smooth experimentation or production.

What are the storage conditions for POTASSIUM FLUORIDE ON CELITE (R)

Potassium and potassium fluoride are loaded on diatomaceous earth (Potassium + Fluoride on Celite ®), and their storage conditions are quite important. This agent should be placed in a dry and cool place, away from direct sunlight. Exposure to sunlight or cause temperature increase will affect its chemical stability.

Furthermore, it should be stored in a well-ventilated place. Good ventilation can prevent the accumulation of harmful gases and prevent the transformation of matter due to high humidity. If the humidity is high, the agent may be affected by moisture dissolution, which will damage its efficacy.

Store in a place away from fire and heat sources. Potassium reacts violently when exposed to heat or open flames, and there is a risk of fire and explosion. Potassium fluoride may also change its properties due to high temperature.

This agent should be stored separately, not with acids, oxidants, etc. Due to the high chemical activity of potassium and potassium fluoride, it may come into contact with other chemicals or cause dangerous chemical reactions.

The container used for storage must be well sealed. The sealed container can prevent the agent from coming into contact with the outside air and moisture, and ensure its stable quality. After taking it, it should also be sealed immediately to protect it from the influence of the external environment. In this way, it is necessary to properly preserve the potassium and potassium fluoride loaded on diatomite to ensure its chemical stability and ready to use when needed.

What reactions does POTASSIUM FLUORIDE ON CELITE (R) have with other substances?

Potassium (POTASSIUM) and potassium fluoride (FLUORIDE) are supported by diatomaceous earth (CELITE ®), which are active and easy to react with other substances.

When it encounters acids, such as hydrochloric acid and sulfuric acid, it will produce a violent response. Potassium fluoride is alkaline, and when it encounters acid, it will combine acid and base, produce salt and water, and hydrogen fluoride will escape. The corresponding formula is as follows: $KF + HCl\ longrightarrow KCl + HF $. Hydrogen fluoride is a toxic and rotten gas. It should be used with caution when it is used. It is set to escape in the air and endanger people and things.

When it encounters metal salts, it will also change. In case of copper salts, copper fluoride deposits can be generated. This change is related to the exchange of ions, the translocation of potassium ions with other metal ions, and the formation of new compounds. Taking copper sulfate as an example, it should be as follows: $2KF + CuSO_ {4}\ longrightarrow K_ {2} SO_ {4} + CuF_ {2}\ downarrow $.

In the organic environment, this mixture is also an essential agent. In organic synthesis, it is often used as a medium for fluorination, introducing fluorine atoms into organic molecules. For example, alkenes are co-heated with potassium fluoride-diatomite, and fluorine atoms can be added to ethylene bonds to obtain fluorine-containing hydrocarbons. This should expand the structure of organic compounds, increase their properties and use.

Joined with water, potassium fluoride gradually dissolves, partially hydrolyzes, hydrofluoric acid and potassium hydroxide. Although the degree of hydrolysis is small, it has been placed in the wet air for a long time, and its properties have gradually changed.

In summary, potassium and potassium fluoride are contained in diatomaceous earth. In various chemical environments, due to the properties of fluorine and potassium, they respond to many substances, involving acids, salts, organic matter and water, etc., and the results are specific. They are important in chemical research and industrial production. When used, they must know their properties in detail and be careful to avoid danger.
