Bromine is one of the important chemical raw materials and the main branch of the marine chemical industry. A wide variety of inorganic bromides, bromates and bromine organic compounds derived from it have special value in the development of national economy and science and technology. With the development of my country's leading industry, it is infiltrating into various industries and fields.
Bromine is an important chemical raw material and is widely used in flame retardants, fire extinguishing agents, refrigerants, photosensitive materials, medicine, pesticides, oil fields and other industries.
The natural resources of bromine mainly exist in seawater, underground concentrated brine, sedimentary rock salt mines of ancient oceans, and salt lake water. Due to the huge amount of seawater, the bromine content in seawater accounts for 99% of the total resources on the earth. The concentration of bromine in seawater is about 65ppm, while the content of bromine in rock salt mines is only 0.1ppm, and the bromine content of underground brine in some areas is 200-300ppm (such as the underground brine in Laizhou, Shandong). The concentration is as high as 2000-12000ppm.
The production capacity of bromine in the world is about 600,000 t/a, and the annual output in recent years is about 400,000 t. The bromine production industry is mainly distributed in the United States (accounting for 40% of the world's total bromine production), Israel (30%), China (10%), and Russia, the United Kingdom, France, Japan (5% in total) and other countries. The world's famous producers of bromine and bromine-derived chemicals include Great Lakes Chemical Company in the United States, Albemarle Company, and Dead Sea Bromine Group in Israel. The bromine production in the United States and Israel both use natural salt lakes as raw materials, so the proportion of bromine extracted from seawater as the initial raw material in the world accounts for about 7%. There are more than 200 bromine chemical manufacturers in my country, with more than 200 varieties, mainly including medicines, pesticides, dyes, flame retardants, fire extinguishing agents, refrigerants, photosensitive materials and other series.
