FAQ

What are the main uses of ammonium fluoride?

The main use of chemical reagents is as raw materials, water reagents, etc. Its original materials can be used for multiplexing and reversing important effects.

In the field of chemical synthesis, chemical reagents are often used to remove trace moisture in the reaction system. Due to the fact that water is used in many reactions, or it can be used for the normal reaction of dry reagents, and even the reaction method can be used to improve the production. When it encounters water, it is a strong reaction, generating a strong oxidation, which can be used for the purpose of water reagents, so as to ensure the dryness of the reaction environment, so that the reaction can be carried out according to the direction of the reaction period.

Furthermore, chemical reagents can be used as raw materials, and some of the original compounds can be reacted. For example, some carbonyl-containing compounds can be reacted to by the original phase of alcohol compounds under the action of chemical reagents. This principle is very important in chemical synthesis, and can assist in the synthesis of a variety of chemical compounds with specific properties, which are used in many fields such as chemistry and materials.

In addition, in metallurgical engineering, chemical chemistry also has its use. It can be used to extract some metals, and remove gold from gold stones by means of its original properties, so as to improve the quality of gold.

In addition, chemical chemistry plays an indispensable role in chemical synthesis, metallurgy and other aspects.

What are the physical and chemical properties of the reagent ammonium fluoride?

The chemical and chemical properties of the chemical and chemical compounds can be studied. The chemical and chemical properties are white crystals. Under normal conditions, the properties are fixed. However, in case of strong reaction of water, the oxidation will be generated. Its reaction is strong, and if it is ignited in a fire, it is not possible.



< its density, general gold compounds, 1.45g/cm ³, this characteristic makes it useful in some specific domains. And its melting height, 280 ℃, under high temperatures, it can still maintain its inherent shape and is not easy to melt, such as the stone in a fire, proudly not.

Furthermore, the chemical has high chemical activity. It can generate many kinds of biological reactions, especially oxidizing substances. This property makes it possible to perform well in a wide range of fields, such as chemical synthesis, catalytic reaction, etc.

In addition, the chemical performance is also good. It can adsorb a large amount of waste under suitable conditions, and it can be released as needed. If it is a waste of water, it can be supplied on demand. This property makes it possible to store a large amount of waste in the field, and it is expected to be used as a solution to the problem.

In addition, due to its physical and chemical properties, chemical production, or new energy exploration, etc., it all hides great value. We need to explore it in depth to reveal its mysterious side, make good use of it, and benefit the world.

What are the precautions for the storage and transportation of reagent ammonium fluoride?

The reagent zinc chloride needs to pay attention to many matters during storage and transportation. It is dry and easy to absorb moisture, so the storage place must be dry, and it should be placed in a closed container to prevent moisture from entering and causing it to deliquescence, damaging its purity and quality.

When transporting, the first thing to ensure is that the packaging is tight and undamaged. Zinc chloride is corrosive. If the packaging is damaged and leaks out, it will not only erode the means of transportation, but also may endanger the safety of transporters and cause accidents. Furthermore, water should be avoided during transportation to avoid moisture, and it must not be transported with wet objects to prevent water triggering reactions.

At the same time, zinc chloride can react chemically with many substances. During storage and transportation, it should not be co-located with active metals such as aluminum, magnesium, etc., nor should it be stored and transported with alkali substances. Otherwise, it is easy to induce chemical reactions or cause danger.

In addition, whether it is a storage place or a transportation vehicle, it is necessary to keep well ventilated. If the ventilation is poor, the hydrogen chloride gas generated by zinc chloride after moisture absorption will accumulate, which will not only corrode the surrounding environment, but also threaten the health of personnel. And in the storage and transportation place, warning signs should be clearly posted to make the relevant personnel aware of its characteristics and potential hazards. When operating, be careful and follow regulations. This will ensure the safety of zinc chloride during storage and transportation and avoid accidents.

What are the safety risks during the use of reagent ammonium fluoride?

There are many safety risks in the use of reagent potassium cyanide, which is a matter of life. The following is your detailed description.

Potassium cyanide is highly toxic. Once it enters the human body, it will quickly combine with iron ions in cytochrome oxidase, making cells unable to uptake and utilize oxygen, causing the cell respiratory chain to be interrupted, which in turn causes severe hypoxia in the body tissue, causing people to coma, convulsion, and even respiratory and heartbeat arrest in a very short period of time. Even a very small amount of ingestion may cause irreversible serious consequences.

Furthermore, potassium cyanide is also harmful to the environment. If it is improperly disposed of during use, it will flow into the environment, causing serious pollution to soil, water, etc. It is difficult to degrade in the environment, will persist for a long time, cause continuous damage to the surrounding ecosystem, and endanger the survival of many organisms. For example, polluted water bodies can cause a large number of aquatic organisms to die and disrupt the water ecological balance.

When handling potassium cyanide, a little carelessness can easily cause leakage. If it leaks in solid form, it will float in the air, and people will be poisoned immediately after inhalation; if it leaks in the form of a solution, it will pollute the ground, water sources, etc. And cleaning up after leakage is extremely difficult, requires professional personnel and special equipment, consumes a lot of manpower and material resources, and may also pose a threat to the health of cleanup personnel.

In addition, potassium cyanide is a strictly controlled chemical. There are strict regulations and regulatory procedures for its production, storage, transportation, and use. Illegal acquisition and use of potassium cyanide is a serious violation of the law, and the perpetrators will face severe legal sanctions.

Therefore, the use of potassium cyanide must be extremely cautious, strictly follow safety operating procedures and regulatory requirements, and must not be slack in the slightest to ensure personal safety and environmental safety.

What are the preparation methods of reagent ammonium fluoride?

There are various methods for making caustic soda solution, which are described in detail as follows.

One is the lime soda ash method. Although this is not detailed in "Tiangong Kaiwu", it is commonly used in the world. The method uses lime (CaO) and hydration to obtain calcium hydroxide (Ca (OH) -2), that is, "when lime meets water, it melts into a slurry, which is a genus of calcium hydroxide". After that, soda ash (Na ² CO 🥰) is dissolved in water and mixed with calcium hydroxide slurry. The reaction is: Na ² CO 🥰 + Ca (OH) 🥰 = CaCO 🥰 + 2NaOH. When it sinks, take the supernatant solution, which is the liquid of caustic soda. " The two are mixed, and the sinking one is calcium carbonate, floating on the supernatant liquid, and caustic soda is present ".

The second is the membrane electrolysis method. This requires a saturated solution of table salt (NaCl). In the electrolytic cell, an electric current is passed, and the chloride ions at the anode lose electrons and form chlorine (Cl2) to escape, that is," at the anode, chlorine loses electrons, and chlorine gas is generated and escapes "; at the cathode, water gains electrons, and hydrogen is generated and hydroxide is produced". Sodium ions (Na) pass through the diaphragm to the cathode region and combine with hydroxide to obtain sodium hydroxide (NaOH). " Sodium ions pass through the membrane, and they coalesce with hydroxide, and caustic soda becomes ".

The third is the ion exchange membrane method. It also starts with salt saturation, and then the cathode and anode are separated by an ion exchange membrane in the tank. The anode loses electrons to generate chlorine, and the cathode water gains electrons to generate hydrogen and hydroxide. Sodium ions pass through the membrane to the cathode, and combine with hydroxide to form caustic soda. This membrane only allows sodium ions to pass through, blocking other particles and making caustic soda purer." The ion membrane allows only sodium ions to pass through, and the rest block it, so the caustic soda is pure ".

The liquid of caustic soda made by various methods has its own length, and the user should choose according to the situation.
