Carbon dioxide is a colorless, odorless, tasteless and non-toxic gas. Melting point -56.6°C (0.52MPa), boiling point -78.6°C (sublimation), density 1.977g/L.
Carbon dioxide has a wide range of industrial uses.
Dry ice can be obtained by liquefying carbon dioxide into a colorless liquid under a certain pressure, and then rapidly solidifying under low pressure. Its temperature is minus 78.5 ℃. Because of its very low temperature, dry ice is often used to keep objects frozen or cryogenic.
Carbon dioxide is recovered from many different sources. It is obtained as an off-gas from fermentation processes, lime-stone kilns, natural CO2 springs, as well as gas streams from chemical and petrochemical operations. Recently, CO2 is also recaptured from the off-gas from power plants.

High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis; gaseous carbon dioxide is used for carbonated beverage addition, pH control, chemical processing, welding gas; solid carbon dioxide (dry ice) is widely used in food refrigeration, etc.
Yes. Greenhouse gases refer to some gases in the atmosphere that absorb solar radiation reflected from the ground and re-emit the radiation, such as water vapor, carbon dioxide, most refrigerants, etc. They warm the earth’s surface and heat the air in the greenhouse.
There are many sources of carbon dioxide emissions, including: ① combustion of fossil fuels (coal, oil, natural gas); ② production and processing of coal and oil; ③ animal respiration and feces; ④ plant respiration and humic acid fermentation; ⑤ Fermentation and decay of organic matter (animals, plants); ⑥ Volcanic eruptions, forest fires, etc.
