High Quality Cas No.: 75-21-8 Pricelist – Carbon Dioxide (CO2) – Taiyu

Technical parameters

Carbon dioxide, a kind of carbon oxygen compound, with the chemical formula CO2, is a colorless, odorless or colorless odorless gas with a slightly sour taste in its aqueous solution under normal temperature and pressure. It is also a common greenhouse gas and a component of air. One (accounting for 0.03%-0.04% of the total volume of the atmosphere). In terms of physical properties, carbon dioxide is a colorless and odorless gas at room temperature and pressure. It has a higher density than air and is soluble in most organic solvents such as water and hydrocarbons. In terms of chemical properties, one of carbon dioxide carbon oxygen compounds is an inorganic substance. It is chemically inactive and has high thermal stability (only 1.8% decomposition at 2000°C). It cannot burn, usually does not support combustion, and is acidic. Oxides have the same properties as acidic oxides. Because they react with water to produce carbonic acid, they are anhydrides of carbonic acid. Regarding its toxicity, studies have shown that low-concentration carbon dioxide is not toxic, while high-concentration carbon dioxide can poison animals. High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis, carbon dioxide lasers, calibration gas for testing instruments and the preparation of other special mixed gas, and it is used as a regulator in polyethylene polymerization. Gaseous carbon dioxide is used for carbonized soft drinks, pH control in water treatment processes, chemical processing, food preservation, inert protection in chemical and food processing, welding gas, plant growth stimulant, used in hardening molds and cores and used in casting Pneumatic devices are also used as a diluent for sterilization gas (ie, a mixture of ethylene oxide and carbon dioxide is used as a sterilization, insecticide, and fumigant. It is widely used in the sterilization of medical appliances, packaging materials, clothing, fur, bedding, etc. , Bone meal disinfection, fumigation of warehouses, factories, cultural relics, books). Liquid carbon dioxide is used as a refrigerant, low-temperature tests of aircraft, missiles and electronic components, to improve oil well recovery, rubber polishing and chemical reaction control, and can also be used as a fire extinguishing agent.
