| Description | Carbon dioxide is a common compound in air, the carbon reacts with oxygen and its chemical formula is CO2, a carbon dioxide molecule from the two oxygen atoms and one carbon atom by a covalent bond structure, at room temperature is a colorless, odorless gas is heavier than air , can be dissolved in water, carbonic acid reacts with water, does not support combustion. After the solid carbon dioxide compression known as dry ice. Carbon dioxide is considered to be the main source of the greenhouse effect. Preparation by the decomposition of calcium carbonate under intense heat on the industry. |
| Usage | Carbon dioxide has a very wide range of uses. Products are mainly carbon dioxide, fermentation gas, lime kiln gas, sour gas, a side reaction of ethylene oxide gas and other gases in the flue gas extraction and recovery of hydrogen from ammonia process gas system, the purity of the commercial product is not less than 99% (by volume) . |
| Precautions | Carbon dioxide, the air density is larger, the carbon dioxide is small when no harm to the human body, but it will affect the person exceeds a certain amount (other organisms also) breathing, because the carbonic acid concentration in the blood increases, the acidity and produce acidosis. The volume fraction of carbon dioxide in the air is 1%, the feeling of tightness, dizziness, palpitations; feel dizzy when 4% -5%. More than 6 percent when people delirious, gradually stop breathing and even death. |
