Expanded information1, the physical and chemical properties of carbon dioxide
Carbon dioxide (carbon dioxide), a carbon-oxygen compound, the chemical formula for CO2, the chemical formula amount of 44.0095, at room temperature and pressure is a colorless and tasteless or colorless and tasteless and slightly acidic gas, but also a common greenhouse gases, but also one of the components of the air (0.03%-0.03% of the total volume of the atmosphere), and also one of the components of the air (0.03%-0.00% of the total volume of the atmosphere). It is also a common greenhouse gas and one of the components of air (0.03%-0.04% of the total volume of the atmosphere).
In terms of physical properties, the boiling point of carbon dioxide is -78.5 ° C, melting point is -56.6 ° C, the density is greater than the density of air (under standard conditions), soluble in water. In terms of chemical properties, carbon dioxide is chemically inactive, thermally stable (only 1.8% decomposition at 2000 ℃), can not be burned, and usually does not support combustion, belongs to the acidic oxides, with acidic oxides in general, because the reaction with water to produce carbonic acid, so it is the carbonic acid anhydride.
2, the preparation of carbon dioxide
Carbon dioxide can be generally calcined limestone or limestone and dilute hydrochloric acid reaction by high temperature, mainly used in cold storage of perishable food (solid), as a refrigerant (liquid), the manufacture of carbonated soft drinks (gaseous) and for the homogeneous reaction of solvents (supercritical state) and so on.
3, carbon dioxide storage
Carbon dioxide is suitable for storage in a cool, ventilated non-flammable gas special warehouse, suitable for shipment in liquid or solid form. Storage, transportation of carbon dioxide need to pay attention to the following points: ① away from fire, heat sources, the warehouse temperature should not exceed 30 ℃; ② and flammable (combustible) stored separately, do not mix storage; ③ storage area should be equipped with emergency equipment for leakage.
