What is the role of sodium oxide and what are the uses of sodium oxide?

It is mainly used as a compound for the preparation of sodium, or as a bleaching agent, disinfectant, dehydrogenator, polymerizer for chemical reaction, condensation agent, etc.

Sodium oxide is one of the components of red mud, accounting for 2-10% of red mud, and can be used together with alumina**. In the industry, there are two methods: acid method and alkali method to convert the sodium oxide in the red mud into other substances and carry out the process and play its role. The acid method is to add acid gas or hydrochloric acid to the red mud, precipitate and separate silica, and then ** sodium oxide.

There are two methods of alkali method: calcium oxide method and sodium carbonate method.

The calcium oxide method can be operated at both atmospheric and high pressures. At atmospheric pressure, the main components in red mud can react with calcium hydroxide to form sodium calcium aluminosilicate hydrate at atmospheric pressure and a certain temperature. Under high pressure, there are mainly methods such as high-pressure hydration method and hydrothermal method.

The high-pressure hydration method is to add lime at a temperature of 280 300, treat the red mud with a high k (that is, the molecular ratio of sodium oxide and alumina in solution) solution, and dissolve it to obtain a sodium aluminate solution with k of 12 14.

This method can synthesize the alumina and sodium oxide in it, in which the sodium oxide becomes aluminum hydroxide, and the sodium oxide can be recycled. The hydrothermal method uses k = 40 or so solution to treat red mud, the ** rate of sodium in red mud can reach 80% 90%, but the ** rate of alumina is low, only 10% 20%, and the aluminum-silicon ratio of red mud after treatment is still greater than 1.

The sodium oxide in the red mud is converted into sodium aluminate and sodium ferrite at a high temperature of more than 1000 in the sodium carbonate method.

It meets the equation for water: Na2O+H2O=2NaOh

Hello, this friend, I will give you your problem According to your description, the problem is relatively clear, because the dog's absorption is on the tongue, so do not supplement a lot of salt at once. Okay, that's pretty much it, if you still have any questions, please continue to consult. Thank you for the follow-up:

Did the dog eat it and burn his internal organs and suffocate directly? : If the concentration is high, it is also caused by excessive absorption.

Remember. Follow-up question: How much can you suffocate a dog on one side?

When you're suffocated, throw away all the entrails and everything. Then there will be nothing wrong with people who eat dog meat: can you bear to eat it?

Of course it won't be fine. Follow-up: Thank you very much!

What are the uses of sodium hydroxide?

Sodium oxideUsage:It is used as a compound for the preparation of sodium, or as a dehydrogenator, a polymerizer for chemical reactions, a condensation agent, etc.

Storage precautions: Store in a ventilated and low-temperature warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The package is sealed. It should be stored separately from acids and edible chemicals, and should not be mixed. The storage area should be equipped with suitable materials to contain the spill.

During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or damage. It is strictly forbidden to mix with acids, edible chemicals, etc. During transportation, the transport vehicle should be equipped with leakage emergency treatment equipment.

During transportation, it should be protected from exposure to sun, rain and high temperature. When transporting by road, it is necessary to drive according to the prescribed route and do not stop in residential areas and densely populated areas.

Preparation method of sodium oxide:

with pure sodium azide.

Sodium oxide can be prepared by mixing and heating with nano3. First, a thin layer of pure sodium azide is placed on the nickel disc. Then put the sodium nitrate.

Mix well with sodium azide, grind into a fine powder, and load it into a nickel disc. The nickel disc is placed in a rigid glass tube.

Vacuum with a mercury diffusion pump, and at the same time turn on the electric furnace to slowly raise the temperature to 200, remove the moisture attached to the surface of the reaction mixture, and gradually increase the temperature to 270-290, the heating rate should not be too urgent, otherwise it will cause **. to the vacuum pump.

The can be opened or closed to control the progress of the reaction.

When the temperature continues to rise, nitrite is generated.

The mixture has a brown color. When the brown color disappears and the gas stops being produced, the temperature rises to 350-400, the excess sodium is evaporated in a vacuum, and the sodium mirror at the glass tube is heated with a flame to remove. Cool the glass tube and remove the nickel pan.

Be careful not to touch any part of the plate with sodium to prevent sodium from condensing on the Na2O in the plate, and strictly isolate the air. Sodium oxide can be prepared within 3-5h according to the above operations.
