Propylene carbonate (molecular formula: C4H6O3) is a colorless, odorless, flammable liquid. Miscible with ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. It has a strong ability to absorb carbon dioxide and is stable in nature. In industry, it is obtained by adding propylene oxide and carbon dioxide under a certain pressure, and then distilling under reduced pressure. It can be used as oily solvent, spinning solvent, olefin, aromatic hydrocarbon extractant, carbon dioxide absorber, dispersant for water-soluble dyes and pigments, etc.
Application
1. It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry.
2. In the polymer industry, it can be used as a solvent and plasticizer for polymers.
3. Used as a plasticizer for adhesives and sealants.
4. It can also be used as a phenolic resin curing accelerator and a dispersant for water-soluble adhesives, pigments and fillers.
5. The chemical industry is the main raw material for synthesizing dimethyl carbonate. It can also be used to remove
carbon dioxide and hydrogen sulfide from natural gas and petroleum cracking gas.
6. It can also be used in textile, printing and dyeing and other industrial fields.
Calcium is a silvery white metal that is harder and heavier than lithium, sodium, and potassium;
It melts at 815 C. The chemical nature of metallic calcium is very active. In the air, calcium is quickly oxidized and masked with an oxide film. When heated, calcium will burn and emit a beautiful glow of brick red. Calcium and cold water have a slower effect, and intense chemical reactions occur in hot water to release hydrogen (lithium, sodium, and potassium can cause intense chemical reactions even in cold water). Calcium is also easily combined with halogens,
sulfur, nitrogen, and the like.

Product use:
At present, in the steel industry, the main use of metal calcium is to process into metal calcium particles, and then to make calcium iron wire or pure calcium wire, and finally used for steel refining outside the furnace, its role is to desulfurization, deoxidation, increase the fluidity of molten steel. Promote the rapid rise of inclusions in molten steel, generally used in the production of high-quality steel; as a dehydrating agent to produce anhydrous alcohol; in the petroleum industry, as a desulfurizing agent, in the metallurgical industry, it is used to deoxidize or
desulfurize . However, calcium compounds have a very wide range of uses, especially in the construction industry.
