As one of the important chemical raw materials, bromine is widely used in many industries, and its uses are countless. Bromine price manufacturers will introduce to you again.
1. A large amount of bromine is used in the petroleum industry to produce dibromoethylene (or dibromoethane), which is used as an antiknock agent for petroleum fuels. Although a small amount is added, it can better eliminate lead oxide fouling in the engine cylinder.
2. Used in the pharmaceutical industry to produce sedatives such as sodium bromide and calcium bromide, mercuromelic syrup, and hormone intermediates for the manufacture of chloramphenicol, chloramphenicol and vitamin A.
3. It is an important raw material for the manufacture of effective low-toxic fire extinguishing agent 1211 in the national defense and fire-fighting industries.
4. In the dye industry, bromine is used to make pigments such as eosin and tetrabromo indigo.
5. Bromine uses a large amount of silver bromide as a photosensitive drug in photography and film technology.
6. In the manufacture of pesticides, the role of bromine is used to manufacture fumigants and pesticides.
7. Bromine can also be used to make various chemical products, such as sodium bromite and potassium bromate, which can be used as a benchmark reagent in analytical chemistry. Lithium bromide can be used as an absorption refrigerant.
I believe everyone is familiar with the basic knowledge of bromine. Today, our bromine price manufacturer will focus on the distinction between bromine and bromine water. I believe that many friends will have questions when they see this title. Both bromine and bromine water are bromine. It Is there a difference between the two? I want to tell everyone here that although bromine and bromine water have similarities, they are completely different.
1. Bromine (liquid bromine, Br2) is a dark red-brown liquid, and bromine vapor is a red-brown gas.
2. Bromine water is an orange-yellow liquid (a solution of bromine, the main component is Br2).
3. Bromine vapor and nitrogen dioxide can be identified by adding water, silver nitrate solution, carbon tetrachloride, etc. Silver nitrate reacts with bromine to form a pale yellow silver bromide precipitate (bromine dissolves in water to form bromine water, containing bromide ions), while NO2 dissolves in water to form nitric acid and nitric oxide, which will not react with silver nitrate.
The above is the method of distinguishing bromine and bromine water introduced by the bromine price manufacturer. I hope this knowledge can help you.
